Identity and belonging in the teen years

"Who am I?" and "Where do I fit?" are two of the biggest questions of the teen years. Teens try out new friends, interests, styles and beliefs. They start to think about culture, faith, gender and sexuality in new ways. This is normal, healthy work, but it can also feel lonely and confusing.

One of the strongest protections for teen mental health is a simple feeling: that people at school and at home care about you. This guide explains why belonging matters so much, who is most at risk of feeling left out, and what teens, parents and schools can do.

What belonging means

School connectedness is the feeling that adults and classmates at school care about you as a person and about your learning. It includes feeling valued, supported and like you belong.³

Belonging can also come from family, a team, a faith community, a cultural group, a club, a job, or an online community. It does not mean being popular. It means having at least a few places where you can be yourself and know that people have your back.

How common is feeling left out?

In CDC's 2023 survey, 55% of U.S. high school students said they felt close to people at their school. That means close to half did not.² Boys were more likely than girls to feel connected, and cisgender and heterosexual students more likely than LGBTQ+ students.²

Earlier CDC data from 2021 showed similar gaps. About 66% of boys felt connected at school, compared with 58% of girls. About 65% of heterosexual students felt connected, compared with about 48% to 55% of lesbian, gay, bisexual and questioning students.⁴ Students who experience racism and students from racial and ethnic minority groups are also more likely to feel less connected.³

Around the world, most 15-year-olds feel they belong at school. But across OECD countries, about 1 in 6 feels like an outsider or left out at school.⁷

Signs a teen may feel they don't belong

• Eating lunch alone or avoiding common spaces
• Saying "No one gets me" or "I don't fit anywhere"
• Dropping activities they used to enjoy
• Spending most free time alone or only online
• Hiding parts of who they are from family or friends
• Not wanting to go to school, or feeling invisible there

Our loneliness test can help you notice how connected you feel. It is not a diagnosis.

Why belonging matters so much at this age

Identity is under construction. Teens are figuring out what they value and who they want to be. Feeling accepted while they explore makes it safer to grow.

Friends become central. Teens care deeply about how peers see them. Rejection can feel unbearable, and acceptance can feel like oxygen.

Connection supports learning. Children and teens with good relationships with peers, parents and teachers do better in school.⁵ Connected students are more likely to attend school, earn higher grades and graduate, and less likely to use substances or face violence.³

The benefits last. Teens who feel connected at school are less likely to have mental health, substance use and violence problems as adults.³

How belonging affects mental health

Belonging is one of the clearest protective factors in teen mental health research. CDC calls feeling connected to school and family the key protective factor for youth.⁸

In CDC's 2023 survey, students who felt highly connected at school had about 30% to 37% lower rates of persistent sadness, poor mental health, seriously considering suicide and attempting suicide.¹ In 2021 data, about 22% of highly connected students reported poor mental health, compared with 40% of students with low connection.⁴ These are links, not proof of cause, but they are strong and consistent.

Loneliness and exclusion work in the opposite direction. WHO lists discrimination, stigma and belonging to a minority or discriminated group among the risks for teen mental health.⁹ For more on loneliness, see our loneliness library.

What helps

Steps to build belonging

1. Name one adult. Write down one adult at school you could go to if something went wrong. If you cannot think of one, ask a counselor to help you find one.
2. Try one thing. Join one club, team, class or group this month. Go at least three times before deciding.
3. Reach out to one person. Send a message, sit with someone new, or ask a classmate to study together. Small moves add up.
4. Find "your people" in more than one place. School, family, an activity, and maybe an online group. If one place feels hard, others can hold you up.
5. Be the welcome you want. Notice who sits alone and say hi. Belonging grows when people make room for others.
6. Explore who you are safely. Read, talk with people you trust, and take your time. You do not need all the answers now. Our values compass and strengths quiz can help.
7. Ask for help if you feel stuck. Shyness, social anxiety or past bullying can make reaching out harder. Support can help. See social anxiety.

For parents and caregivers

• Stay close, even when they pull away. Teens still need you. Eat together, drive together, and show up to their events.
• Know their world. Know where your teen is, who they are with, and who their friends are. This kind of caring attention is linked to lower sadness and suicide risk.¹
• Get involved at school. Stay in touch with teachers and help with schoolwork when you can.⁸
• Make home a safe place to be themselves. Listen without rushing to judge when your teen talks about identity, friends or beliefs.
• Help them find a place. Offer rides, fees or encouragement for activities. Sometimes the first step is the hardest.
• Watch for signs of isolation that last more than a few weeks.

Special situations

LGBTQ+ teens. These teens report much higher rates of sadness and suicide risk.¹ Being LGBTQ+ is not the problem. Stigma and discrimination are well-known risks for teen mental health.⁹ In a 2024 national survey of more than 18,000 LGBTQ+ young people, those in very accepting communities attempted suicide at less than half the rate of those in very unaccepting communities.⁶ Respecting a young person's name and pronouns at home was linked to lower suicide attempt rates.⁶ In July 2025, the 988 Lifeline ended its separate "Press 3" option for LGB+ youth and now serves all callers through its main line.¹²

Teens of color and teens who face racism are more likely to feel less connected at school.³ Cultural clubs, mentors who share their background, and schools that take racism seriously can help.

Immigrant and multicultural families. Teens may feel caught between two cultures or languages. Families can talk openly about this. It is possible to belong to more than one culture.

Teens who are new to a school or town. The first months are often the loneliest. Joining one activity early and asking a counselor for a peer guide can help.

Neurodivergent teens and teens with disabilities may find typical social settings tiring or confusing. Interest-based groups, where people bond over a shared passion, can be a good fit. See our autism and ADHD pages.

Common questions

I don't have any close friends. Is something wrong with me?

No. Many teens go through times without close friends, especially after a move, a change of school, or a falling out. Friendship is a skill and a matter of finding the right place. One shared activity is often the best start.

My teen just told me they are gay or transgender. What should I do?

Thank them for trusting you and tell them you love them. You do not need to have all the answers. Acceptance at home is linked to lower suicide risk for LGBTQ+ young people.⁶

Are online friends real friends?

They can be. Online friendships can offer real support, especially for teens who feel isolated offline.¹¹ It helps to also have at least one person nearby you can see in person.

When to get help

Talk with a doctor, counselor or therapist if loneliness or feeling left out:

• Lasts most days for several weeks
• Comes with sadness, hopelessness or loss of interest
• Leads to skipping school or avoiding people entirely
• Comes with being bullied or rejected because of who you are (see bullying)
