My child has no friends: what's normal, what helps, and when to worry

Loneliness is more common in young people than most parents realise. Teenagers and young adults report it more than any other age group, and for most of them it passes.

There’s a lot of research on loneliness in children and young people. Much of it is reassuring, and it’s clear about what helps. This guide covers what’s normal, what’s not, and what parents can do.

Is it normal for a teenager to have no friends?

Loneliness peaks in the young, not the old. In a large national survey in England, 16 to 24 year olds were more likely than any other age group to say they feel lonely often or always ^[1].

The same pattern holds far beyond England. In the BBC Loneliness Experiment, which surveyed tens of thousands of people around the world, loneliness was again highest in the youngest people and fell steadily with age ^[2]. If your child is lonely right now, a great many young people feel the same.

Two more findings put the worry in proportion. First, lasting loneliness is rare. In a study that followed young people from 10 to 16, fewer than 1 in 100 stayed highly lonely throughout, though a much bigger group grew slowly lonelier ^[3]. Second, loneliness and friendlessness are not the same thing. In a very large study of students, most of those who felt lonely had close friends, and most of those without close friends did not feel lonely ^[4].

The number of friends matters less than many parents fear, too. A large review found that how a child’s friendships go, especially whether they involve conflict or unkindness, was more closely linked to loneliness than how many friends they had ^[5]. A single dependable friend can count for a great deal. And in a large UK study of 14-year-olds, unkind and unwanted relationships were a major source of loneliness in their own right ^[6]. A child who has stepped back from a group that made them miserable may be doing something healthy.

Lonely, or just alone?

Loneliness is the gap between the connection a young person has and the connection they want. It’s a feeling, not a headcount, and it’s not the same as spending time alone. A 2023 study of adults recorded short sound clips from their everyday lives. Time spent alone and feeling lonely were only weakly linked, until someone was alone for more than about three quarters of their waking time ^[7].

Teenagers also need more solitude than they did as children. It’s where identity gets worked out. Young people themselves describe chosen time alone as calming and restorative ^[8]. That’s a different thing entirely from the loneliness they dread.

So the useful question is not how much time your child spends alone. It’s whether the aloneness is chosen, and whether it bothers them. A teenager who is alone and content is usually fine. A teenager who is alone and unhappy about it is lonely, and that’s the situation the rest of this guide is for.

What are the signs a child is lonely?

Loneliness is not a diagnosis, and there’s no checklist. Young people also rarely announce it. A UK study of Childline counselling conversations about loneliness found that difficulty trusting others and low self-worth held young people back from seeking longer-term help ^[9]. Expect signals rather than statements. Things parents commonly notice:

• Lines like "no one likes me" or "everyone already has their group", said lightly or in anger.
• Weekends and school holidays with no contact from anyone, and no plans your child seems able to make.
• Hovering at the edge of arrangements: invited to the group chat but never to the thing itself.
• A dip in mood when other people's plans and photos appear on their phone.
• Reluctance to go to the places where the disconnection is felt, often school.

Loneliness in boys is easy to miss. A large review of studies across all ages found that boys and girls feel lonely about as often as each other ^[10]. Young people also feel more shame about loneliness than older people and are more inclined to hide it, and men are more likely than women to see loneliness as something people look down on ^[11]. It can look instead like irritability, "I’m fine", and gaming into the small hours because that’s where the company is.

Why does a young person end up lonely?

Usually it comes down to circumstances, and bullying has one of the strongest links. In a large international study, loneliness was more than twice as common among teenagers who were bullied, and nearly twice as common among those with no close friend ^[12]. Being bullied at 10 was also linked to the most lasting loneliness in the years that followed ^[3]. If you suspect this is the root, our guide to bullying covers what to look for and how to respond.

Transitions matter too. Starting secondary school, a friendship group reshuffling in the GCSE years, sixth form, leaving for university: each one can dissolve a social world that took years to build. Our guides to starting secondary school and supporting your child at university look at those two stages in detail.

Loneliness and social anxiety can also feed each other: fear of being judged leads to avoiding people, which deepens the loneliness, which in turn sharpens the fear ^[13]. You can read our guides to social anxiety and low self-esteem.

Autistic young people can be more likely to feel lonely. Research comparing groups found autistic young people reported more loneliness specifically in adolescence, and although they reported less wish for social contact overall, their wish to belong grew during adolescence just as it did for other young people ^[14].

In focus groups, autistic and ADHD teenagers put it plainly: being alone can be a good thing, but not when it’s not your choice ^[15]. For these young people, socialising is often exhausting rather than unwanted. One understanding friend changes a great deal.

Changes at home play a part as well. Family upheaval, separation, or illness in the family are all linked to more loneliness in young people ^[16]. That makes steadying things at home, and talking about what has changed, a way of helping in its own right.

Does loneliness matter? What the research shows

The research has two halves, and the reassuring half is just as well evidenced as the other.

First, the risks. Loneliness that lasts is linked to later mental health difficulties. A large review of research on children and young people found that those who were lonely were more likely to develop depression, sometimes years later. There were signs of a link with anxiety too, though the evidence was weaker ^[17].

How long it lasts matters more than how bad it looks on any given day. A miserable fortnight after a falling-out is not the concern. The same flatness still there months later is.

Loneliness is also linked to how young people do at school. In a UK study, young people who were lonely at 12 were more likely to leave school with lower qualifications ^[18]. Lonely young people also tend to miss more school, and anxiety and low mood seem to be a small part of that link ^[19]. If mornings are becoming a battle, our guide to EBSA picks that thread up.

Now the reassuring half. Loneliness often passes, and when it eases, the extra risk seems to ease too. In a study that followed teenagers over time, those whose loneliness had lifted by age 14 had a smaller extra risk of mental health problems at 16 than those who stayed lonely ^[20].

These are patterns across groups, not predictions about your child. Every one of them is exactly what early, well-matched support is for.

What can you do to help a lonely child or teenager?

Listen first, fix later

The instinct might be to solve it: join a club, invite someone round, put yourself out there. Young people often describe that response as pressure. In the Childline analysis, what they wanted first was to feel heard without being judged ^[9]. "That sounds really hard" opens more doors than a plan does. Let your child stay the expert on their own social world, and keep your help low-key rather than turning their friendships into a project.

Stay easy to talk to

This has good evidence behind it. A large Danish study asked young people how easy they found it to talk to their parents. Those who found it very difficult were several times more likely to feel lonely than those who found it very easy ^[21].

During the UK lockdowns, 11 to 16 year olds who felt closer to their parents were less lonely and less distressed ^[22]. Being easy to talk to looks unremarkable up close: car journeys, food, sitting through an episode of something you don’t enjoy. Side by side beats face to face, because it feels more natural and less like an interrogation.

Aim for one connection, not a crowd

Unkind or difficult friendships are more closely linked to loneliness than having few friends, so the goal is one compatible person, not a social circle ^[5]. The route there is usually an activity where the interest does the talking, whether that’s football, art, a coding group, Warhammer, or volunteering. Doing something together takes away the pressure to perform socially, which is exactly what a lonely young person dreads.

For younger children, you can arrange more of this directly: one classmate round for something structured beats a party. For teenagers, your role shrinks to logistics and low-key encouragement. Driving them there is support; briefing them on how to behave is pressure.

Work quietly with school

Teachers see a social world you can’t. In a large study of students across Europe, school factors explained a substantial share of who felt lonely ^[23]. A bullying climate went with more loneliness, and supportive teachers with less. A short, specific conversation with the teacher, form tutor or head of year, asking what they see at break and lunch, often reveals the shape of the problem. Our guide to talking to school about your child’s mental health covers how to have that conversation well.

Phones and gaming: watch the pattern, not the hours

The evidence here is calmer than the headlines. A large review of the research found that time spent on social media had almost no link with loneliness, while compulsive, hard-to-stop use had a moderate one ^[24]. UK studies of teenagers and of young adults agree that what people do and experience online is more closely linked to loneliness than how long they spend on social media ^[25], ^[26].

In practice, a teenager chatting to real friends while gaming is often doing something social, and taking it away can remove their main source of company. The warning signs are use that feels compulsive, anxious or joyless, use that replaces all other contact, and being picked on online.

If your child is 18 to 25

Loneliness doesn’t end at the school gates, and the national figures show it peaks between 16 and 24. University is sold as the most social time of life. That makes a lonely first term feel like a personal failure, when in fact it’s very common. Parents still matter a great deal at this age. In a small study of first-term university students, closeness with parents stayed linked to less loneliness, while the link with friendships faded ^[27].

Practical help looks like regular, undemanding contact and patience through the autumn. Encourage joining one new group or one shift of part-time work rather than a full social reinvention. Our guide for parents of university students covers this stage in more detail, including when a low first term is becoming something that needs more support.

When should you seek help, and how counselling helps

It’s time to look for more support when loneliness seems to be settling in rather than passing, or when your child is clearly distressed by it. The same applies when it arrives with falling mood, rising anxiety, or growing reluctance to go to school. If you’re worried, that’s reason enough to ask for help. A conversation with your GP is a sensible first step, and they can refer on to local NHS services where needed.

If you believe your child is in immediate danger, call 999 or go to A&E. If you’re worried about their safety, contact your GP and ask for an urgent appointment, or call NHS 111 and choose the mental health option. You don’t have to be sure how serious it is before asking for help. If you’re unsure, call NHS 111.

You can also call Samaritans on 116 123 or Childline on 0800 1111, or text SHOUT to 85258. Finding Therapy is not a crisis or emergency service.

Counselling has a specific job to do with loneliness. Persistent loneliness changes how a young person reads the social world. They come to expect rejection and to hear it in neutral moments, until reaching out feels pointless.

Research with people of all ages has found that helping someone change how they read social situations works better than simply giving them more chances to be around others ^[28]. A counsellor can do this one to one, at the young person's own pace, while also helping them build the confidence and skills that friendships need.

The evidence that help works is strong. This is what the largest review so far found:

Research focused purely on under-18s is more recent, and its results so far are promising rather than proven, with approaches that build social and emotional skills looking strongest ^[30].

A review by UK researchers reached a similar conclusion, and added one important point. It recommends that support is tailored to the individual young person, not delivered as a one-size-fits-all programme ^[31]. That’s how our counsellors work: person-centred and integrative, with the approach chosen and blended to fit your child rather than the other way round.

If you think talking to someone would help your child, you can browse our counsellors and choose someone yourself. Every counsellor is qualified and registered with a UK professional body. We’ve vetted every one of them, and we’ve known them for years.

If you’re not sure who would suit your child, you can book a free consultation with Helen Spiers, our Head of Counselling, who can help with a recommendation. We’re a private, paid service with no GP referral needed, and we work with children and young people aged 6 to 25. A first session can be available in as little as 48 hours.
