Quick answer: Signs of an anxiety disorder in teens include constant worry that’s hard to control, avoiding school or social situations, frequent stomachaches or headaches, panic attacks, trouble sleeping, perfectionism, and constant need for reassurance. Everyday nerves come and go. An anxiety disorder lasts for months and gets in the way of school, friendships or family life.
How we put this guide together
Perry Behavioral Health is a residential mental health program in Perry, Georgia, for middle and high schoolers, including teens with anxiety. This guide draws on research from the National Institute of Mental Health (NIMH) and national survey data from SAMHSA. It’s meant to help parents recognize when worry has become something more, not to diagnose.
How common is anxiety in teens?
Anxiety disorders are the most common mental health condition in adolescents. According to NIMH, an estimated 31.9% of adolescents have had an anxiety disorder, with higher rates in girls (38.0%) than boys (26.1%). In SAMHSA’s 2024 national survey, about one in five teens aged 12 to 17 reported moderate or severe symptoms of generalized anxiety disorder in the previous two weeks.
Normal worry vs. an anxiety disorder at a glance
| Factor | Normal worry | Possible anxiety disorder |
| Trigger | A specific event, like a test or tryout | Many situations, or no clear reason |
| How long it lasts | Fades once the event passes | Persists for weeks or months |
| Intensity | Matches the situation | Far bigger than the situation calls for |
| Effect on daily life | Still goes to school and sees friends | Avoids school, activities or people |
| Physical symptoms | Occasional butterflies | Frequent stomachaches, headaches or panic |
1. Worry that won’t switch off
Teens with generalized anxiety worry constantly about school, health, family, the future or things that seem small to adults, and they can’t stop even when they know the worry is out of proportion. You may notice endless “what if” questions or trouble relaxing even during fun activities.
2. Avoiding school, people or situations
Avoidance is one of the clearest signs. A teen might refuse to go to school, skip parties, avoid speaking in class, stop driving, or back out of plans at the last minute. Avoidance brings short-term relief but makes anxiety stronger over time, which is why it’s an important sign to address.
3. Frequent stomachaches, headaches or nausea
Anxiety often shows up in the body. Regular stomachaches, headaches, nausea, a racing heart or muscle tension, especially on school mornings or before social events, can be anxiety when a doctor finds no medical cause.
4. Panic attacks
A panic attack is a sudden wave of intense fear with physical symptoms like a pounding heart, shortness of breath, dizziness, shaking or feeling like something terrible is about to happen. Teens who have panic attacks often start avoiding places where one happened before.
5. Trouble falling or staying asleep
Lying awake replaying the day or worrying about tomorrow is common with anxiety. Poor sleep then makes anxiety worse, creating a cycle that affects mood, focus and energy.
6. Perfectionism and fear of mistakes
Some anxious teens look like high achievers: they redo assignments over and over, spend hours on homework, or fall apart over a less-than-perfect grade. Intense fear of failure or of disappointing others can be a sign of anxiety, even when grades are strong.
7. Constant need for reassurance
Asking the same questions repeatedly, such as “Are you sure it’ll be okay?” or “Are you mad at me?”, and needing constant reassurance from parents can signal anxiety. Reassurance helps briefly, but the worry soon returns.
8. Irritability, meltdowns or anger
Anxiety doesn’t always look like fear. When teens feel overwhelmed, they may become irritable, explosive or tearful, especially when faced with something they dread. Outbursts before school or social events can be anxiety in disguise.
9. Using vapes, alcohol or cannabis to calm down
Some teens use substances to quiet anxiety or get through social situations. This can quickly become a habit and make anxiety worse in the long run. If your teen says they vape or use cannabis “to relax,” anxiety may be part of the picture.
What helps teens with anxiety
Anxiety disorders are very treatable. Cognitive behavioral therapy, which helps teens change anxious thinking and gradually face fears, is one of the most effective approaches, and medication can help some teens. Parents play a big role: gently encouraging your teen to face fears instead of avoiding them, and modeling calm responses.
When anxiety leads to school refusal, panic, substance use or worsening depression, and weekly therapy hasn’t helped, a higher level of care may be needed. Perry Behavioral Health provides residential treatment for teen anxiety, with daily schooling so teens stay on track academically. Call (478) 324-4948 to talk through your options.
FAQ
What are the signs of anxiety in a teenager?
Common signs include constant worry, avoiding school or social situations, frequent stomachaches or headaches, panic attacks, trouble sleeping, perfectionism, needing constant reassurance, irritability, and using substances to calm down. When these last for months and interfere with daily life, they may point to an anxiety disorder.
Is it normal for teens to have anxiety?
Some worry is a normal part of adolescence, especially around tests, friendships and big changes. It becomes a concern when the worry is out of proportion, lasts for weeks or months, and causes your teen to avoid school, people or activities.
