Loneliness

Loneliness is one of the hardest emotions to admit
It feels shameful, because everyone around you appears to be coping and belonging somewhere. Admitting loneliness feels like admitting that no one wants to be with you. But that’s not true. Loneliness is not a sign that something is wrong with you. It is a human experience that touches surprisingly many of us.

This page is a comprehensive guide to loneliness. We’ll go through what loneliness is, what it feels like, what causes it, and how to learn to live with it. You’ll also find links to deeper articles that cover different aspects of loneliness in more detail.
What is loneliness, really?
Loneliness is the experience that connection with others is missing or insufficient. It’s the gap between the relationships we wish for and the ones we actually have. This gap can concern the number of relationships, their quality, or both.

An important distinction is between loneliness and being alone. Being alone is a physical state, and it can be entirely voluntary and restorative. Many people enjoy their own time and need it. Loneliness, on the other hand, is a feeling that can prevail even when surrounded by people. You can sit in a full restaurant, be at work surrounded by colleagues, or sleep next to your spouse and still feel alone.

According to research, about one in three people experience loneliness at least occasionally. Among young adults, the figure is even higher. Yet loneliness is rarely discussed openly, because it carries stigma. No one wants to admit to being lonely because they fear being seen as somehow a failure.

But loneliness is not failure. It’s a signal that tells you of a need for connection, the same way hunger tells you of the need for food. It’s a biological and psychological message that deserves to be heard.
Different forms of loneliness
Loneliness is not a single uniform experience. It can manifest in many different ways, and recognizing different forms helps you better understand your own situation.
Social loneliness
Social loneliness means that social networks are too small or too superficial. A person doesn’t have a circle of friends they feel they belong to, or a group to spend time with. Social loneliness is often more easily recognized because it can be linked to concrete things: no one calls, weekends are empty, no one invites you anywhere.

Social loneliness can result from moving to a new city, life changes such as retirement, or from friendships that have gradually faded in life’s busy pace.
Emotional loneliness
Emotional loneliness is often harder to put into words. It means the absence of close, deep connection. A person may have many acquaintances and friends, but no one seems to truly understand. There’s no one to whom you could tell everything, no one who knows you through and through.

Emotional loneliness feels like emptiness and longing. It’s the feeling that no one sees the real you. This experience can be particularly heavy because the situation looks fine from the outside. Social life exists, but depth is missing.
Emotional loneliness in a relationship
One of the most common and least talked about forms of loneliness is emotional loneliness in a relationship. Loneliness in a relationship feels especially confusing because at your side is the person who should be the closest. How can you be lonely when you’re not alone?

Loneliness in a relationship arises when emotional connection with your partner has broken or weakened. Conversations revolve around practical matters, sharing emotions has stopped, touch has decreased or become mechanical. The feeling of not being heard or understood by your own partner is a source of deep loneliness.

Loneliness in a relationship doesn’t mean the relationship is necessarily bad or that you should leave. It means the connection needs care. This is possible, but requires both partners’ willingness and courage to face the situation.
Spiritual loneliness
Spiritual loneliness relates to the experience of meaningfulness. It’s the feeling of not belonging to something larger, of your own life having no purpose, or that no one shares the same values and thoughts. Spiritual loneliness can relate to existential questions, but also simply to not feeling a sense of belonging to the surrounding community.
Loneliness symptoms — how to recognize loneliness
Loneliness doesn’t always identify itself as loneliness. It can disguise itself as many other feelings or symptoms. The following signs can indicate loneliness:
Psychological symptoms

Constant feeling of emptiness
Feeling that no one understands
Difficulty trusting people or letting them get close
Sadness and tearfulness
Lack of motivation and withdrawal
Feeling of being an outsider, even when in company
Feelings of envy toward others’ relationships
Decreased self-esteem

Physical symptoms
Research has shown that prolonged loneliness also affects the body. It activates stress responses and weakens the immune system. Physical symptoms can include:

Sleep problems and fatigue
Changes in appetite
Headaches and muscle tension
Weakened immunity
Elevated blood pressure

Loneliness symptoms often resemble depression symptoms, and prolonged loneliness can lead to depression. Anxiety also often walks alongside loneliness. If loneliness causes anxiety and the feeling is constant, it’s important to take it seriously.
What causes loneliness?
There’s rarely a single cause behind loneliness. It’s often the sum of many factors.
Life changes and transitions
Moving to a new place, starting or finishing studies, divorce, the death of a loved one, retirement, or changing jobs can all lead to loneliness. Familiar social networks change, and building new ones takes time. In these situations, loneliness is a natural transition phase, but it can become prolonged if new connections don’t form.

Retirement in particular is an underestimated major change. Workplace social relationships, which have been taken for granted, disappear overnight. Empty space comes into days that you don’t know how to fill. Similarly, becoming a parent can suddenly increase loneliness: life revolves around the child, and one’s own social relationships go untended.
Social skills and shyness
For some people, relationships involve fears and uncertainty that make creating connection difficult. Social anxiety, shyness, or the experience of not knowing how to act in social situations can lead to isolation. This doesn’t mean they don’t want to be with people, but that it feels too scary or burdensome.

Self-esteem significantly affects how easily a person forms and maintains relationships. Weak self-esteem makes you question your own value in others’ eyes. “Why would anyone want to be with me?” is a thought that prevents opening up and approaching others.
Societal factors
Loneliness is also a societal phenomenon. We live in an era where people live alone more than before, move far from their hometowns for work, and stay in touch more through screens than face-to-face. Social media creates a paradox: we’re constantly connected, but the connection is often superficial. Others’ seemingly perfect lives on screen can deepen one’s own experience of loneliness.
Mental health challenges
Loneliness and mental health intertwine in many ways. Depression reduces energy and the desire to stay in touch with others. Anxiety makes social situations frightening. These conditions can both cause loneliness and be its consequences. A cycle is created where loneliness worsens mental health challenges, which in turn increase loneliness.
Male loneliness — the silent burden
Male loneliness deserves special attention because it’s one of the least talked about forms of loneliness. Men are still often expected to cope alone, keep their feelings inside, and be independent. Asking for help or admitting loneliness feels impossible for many men.

According to research, men lose friendships more easily over the course of life than women. A middle-aged man may notice he doesn’t have a single close friend to call. Maintaining social relationships may have been left to a spouse, and after divorce, networks collapse.

Male loneliness shows up in statistics in stark ways. Men living alone have higher health risks than the general population. Substance abuse, mental health problems, and suicides are more common among lonely men.

The situation is not hopeless, however. More attention has begun to be paid to male loneliness, and many places have peer support groups and gathering spots aimed at men. Just recognizing loneliness and daring to admit it to yourself is a significant step.

If you recognize yourself in this description, know that you’re not alone. Read more on this topic in our article: Male loneliness — why men end up alone and what can be done about it
Why am I lonely?
This is a question many people carry with them. It often contains hidden additional questions: “Is something wrong with me? Am I somehow broken? Why do others succeed but I don’t?”

Loneliness doesn’t result from no one wanting to be with you. It can result from circumstances, timing, learned patterns, or simply not yet having found those people with whom genuine connection arises. It can also result from protecting yourself too much because you’ve sometimes been rejected or abandoned.

Understanding the causes is the first step toward change. The causes of loneliness don’t always need to be analyzed alone. Sometimes an outside perspective helps see blind spots in your own behavior patterns. Read a deeper exploration of this topic: Why am I lonely? Understanding the root causes of loneliness
When loneliness causes anxiety — loneliness’s impact on mental health
Loneliness causes anxiety, and there’s a biological explanation for it. Humans as a species are dependent on community, and our brain’s warning system interprets social isolation as a threat. Loneliness activates the same brain areas as physical pain. So loneliness literally hurts.

When prolonged, loneliness can lead to serious mental health problems:

Depression symptoms increase
Anxiety and social anxiety grow
Self-esteem weakens
Sleep disorders become more common
Substance use can increase
Cognitive functions decline

In chronic loneliness, a person can also begin to interpret social situations more negatively. A neutral glance on the street feels hostile, a colleague’s busyness is interpreted as rejection, a friend’s cancellation as a sign that they don’t care. This negative interpretation bias strengthens loneliness and makes approaching others even harder.

It’s important to understand that loneliness is not a personality trait or permanent quality. It’s a state that can change. But when prolonged, it often requires conscious work and support. If anxiety or depression walks alongside loneliness, treating these together is important because they intertwine.

How to cope with loneliness?
You can cope with loneliness. It’s not a permanent state, even though it feels that way. Change requires time and small, repeated steps, but it’s possible.
Understanding the loneliness cycle
Before talking about solutions, it’s important to understand loneliness’s self-reinforcing nature. Loneliness changes the way we interpret the world. Someone who has been lonely for a long time begins, without noticing, to expect rejection and look for signs that they’re not welcome. This leads to caution and withdrawal, which in turn reduces opportunities for connection. The cycle strengthens.

Breaking the cycle starts with recognizing its existence. When you understand that loneliness distorts interpretations, you can consciously challenge your own assumptions. “They didn’t reply to my message because they don’t want to be in touch with me” can in reality be “they didn’t reply because they were busy.”
Small actions first
Breaking loneliness doesn’t require big actions. Rather, small, regular actions build connection over time:

Greet your neighbor in the hallway
Visit the same café regularly
Respond to invitations, even when social anxiety tempts you to cancel
Join a hobby group or course where you see the same people repeatedly
Reach out to an old friend, even if time has passed

Building connection requires repetition. According to research, becoming friends requires about 50 hours of time spent together. That’s why groups and hobbies where you meet the same people regularly are the most effective remedies for loneliness.
Peer support for loneliness
Peer support around loneliness can be a particularly powerful experience. Just knowing that you’re not the only one struggling with loneliness can ease the feeling. Peer support groups can be found both in person and online. Mental health organizations, religious communities, and many associations organize groups for those experiencing loneliness.

There’s something unique about peer support: another person’s recognizing gaze when you tell your experience. The feeling that someone truly understands because they’ve been in the same situation. It can be the first experience of connection in a long time.
Professional help
If loneliness has become prolonged, is linked to depression or anxiety, or feels insurmountable, professional help is recommended. In therapy you can safely explore the root causes of loneliness: are there fears in the background that haven’t been processed? Did you learn in childhood that people can’t be trusted? Is self-esteem so weak that you don’t dare show up as your real self?

Cognitive behavioral therapy is research-proven effective also in treating loneliness. It helps identify and change thought and action patterns that maintain loneliness.
Digital tools
Sometimes the first step is the hardest: saying out loud that you’re lonely. Not everyone is ready to tell another person, and that’s understandable. Digital tools can offer a low-threshold way to start processing your own emotions.

If you’re looking for a safe space where you can put your loneliness into words without fear of judgment, try Aichologist. It’s an AI-based conversation partner available 24/7. You can talk freely at your own pace, without queues or appointments.
Loneliness test — how lonely are you?
Many people wonder if their own loneliness experience is “normal” or whether they should be worried. The intensity of loneliness can be assessed with a few questions:

Do you often feel that you have no one to talk to about important things?
Do you feel like an outsider in social situations?
Do you long for company and connection but don’t know where to find it?
Is it difficult for you to trust people or let them close?
Does it feel like no one truly knows you?
Has the feeling of loneliness lasted more than six months?
Does loneliness affect your daily life, sleep, or mood?

The UCLA Loneliness Scale is the most commonly used loneliness measure in research. It measures subjective loneliness experience through 20 questions. The test result is not a diagnosis, but it can help understand the situation and serve as a basis for discussion with a professional.

If you answered yes to several of the above questions, your loneliness deserves attention. It doesn’t mean you’re somehow broken. It means your human need for connection isn’t being fulfilled, and something can be done about it.
How to support a lonely loved one?
If you suspect that someone close to you is lonely, you have the opportunity to make a significant act. Breaking loneliness from the outside is often easier than from within.

Reach out proactively. A lonely person may not dare to reach out themselves because they fear being a burden. A simple “how are you?” message can mean more than you imagine.

Be patient. If someone has been lonely for a long time, building trust takes time. They may cancel meetings, seem distant, or test whether you really want to be their friend. Don’t give up too easily.

Avoid minimizing. “Join some hobby” or “just go talk to people” are advice that don’t help. The lonely person has probably already considered these options. Instead, offer something concrete: “Want to go for a walk together tomorrow?”

Invite them along. One of the most effective ways to help a lonely person is to invite them to everyday things. You don’t need to organize anything special. Going to the grocery store together, lunch meetings, or shared walks are all valuable.
You can cope with loneliness
If you’ve read this far, I want to tell you something important: your loneliness is not shame. It doesn’t tell anything negative about you as a person. It tells you that you’re a human being who needs connection with other people, and there’s nothing wrong with that.

Loneliness can feel like a permanent state, but it’s not. People find new friends in all stages of life. Relationships deepen when invested in. Connection is born when you dare to show up vulnerable.

Change starts with small actions. It can start by reading an article that helps you better understand your situation. It can start by talking about your feelings with someone, even if that someone is an AI-based conversation partner. The most important thing is that you don’t stay alone with your loneliness.

Try Aichologist and take the first step. It’s a safe place to put your feelings into words, without judgment or rush.
Frequently asked questions about loneliness
Is loneliness the same as being alone?
No. Being alone is a physical state in which a person is by themselves. It can be voluntary and restorative. Loneliness, on the other hand, is a subjective experience of lack of connection that can prevail even in company. A person can enjoy being alone without feeling lonely, and conversely experience deep loneliness when surrounded by people.
Can you be lonely in a relationship?
Yes, and it’s more common than many believe. Loneliness in a relationship arises when emotional connection with your partner has weakened. Communication has decreased, sharing emotions has stopped, or partners have grown apart. This is often fixable, but requires active investment from both and sometimes professional support.
Is loneliness dangerous to health?
According to research, prolonged loneliness is a health risk that has been compared to smoking 15 cigarettes a day. It raises the risk of cardiovascular diseases, weakens the immune system, increases inflammation in the body, and affects cognitive functions. Loneliness is also a significant risk factor for depression and anxiety. These research findings aren’t meant to scare, but to show that addressing loneliness is important.
Why does loneliness feel so shameful?
There’s cultural stigma around loneliness. Society values sociability and networking, and loneliness is easily interpreted as failure. Many think loneliness results from some defect in themselves. In reality, loneliness is a normal human experience that can affect anyone as life circumstances change. Dismantling the shame begins with talking about loneliness more openly.
Does social media help with loneliness?
Research evidence is mixed. Social media can help maintain connections, but passive scrolling and comparing yourself to others can worsen loneliness. If social media is the primary way of staying in touch, it often remains superficial and doesn’t fulfill the need for deep connection. Face-to-face or at least real-time interaction is more effective in alleviating loneliness.
How do I find new friends as an adult?
Making friends as an adult is possible, although it requires more conscious investment than in childhood or student years. The most effective ways are regularly meeting groups and hobbies where you meet the same people repeatedly. Volunteer work, courses, sports clubs, and peer support groups offer natural opportunities. The key is repetition: single encounters rarely lead to friendship, but regular shared activity gradually deepens the relationship.
When should you seek professional help for loneliness?
Professional help should be sought if loneliness has continued for a long time (more than six months), it significantly affects daily functioning, it involves symptoms of depression or anxiety, or if you notice yourself isolating more and more. Also if you’ve tried to change the situation on your own without results, a professional can help identify patterns that maintain loneliness. The first contact can be with your healthcare provider or a crisis helpline in your country.
Can loneliness result from childhood experiences?
Yes. Childhood attachment relationships shape the way we connect with others. If early relationships were insecure, rejecting, or inconsistent, it can affect adult relationships. The experience of insecurity can manifest as difficulty trusting others, fear of being rejected, or a tendency to withdraw before the other person can leave. These patterns can be changed, but it often requires conscious work, preferably with professional support.
