Anxiety in kids and teens doesn’t always show up as obvious fear. It often appears as stomachaches, sleep problems, irritability, school avoidance, constant worry, or pulling away from friends and activities. These symptoms can build gradually and may start affecting daily life before a child or teen can explain what they’re feeling. Paying attention to patterns—not just isolated moments—can help parents decide when extra support could be helpful.
Parents and caregivers often notice anxiety in small ways at first: a child who suddenly can’t sleep alone, a teen who dreads school, a “clingy” phase that doesn’t pass, or frequent headaches on weekday mornings. If you’re asking yourself whether these changes are typical stress or common anxiety symptoms in children or teens, we can help.
If you’re looking for mental health treatment in Los Angeles for a child or teen, HillsidesCares supports youth ages 6–17 through multiple levels of care and family-centered programming.
How common is anxiety in teens and kids?
Anxiety is one of the most common mental health concerns for adolescents. The National Institute of Mental Health (NIMH) estimates that 31.9% of adolescents ages 13–18 experience an anxiety disorder at some point, with higher prevalence among females than males.
What matters most for parents isn’t just how common anxiety is, but how much it interferes with daily life. If worry, fear, avoidance, or physical stress symptoms start affecting sleep, school, friendships, or family routines, it’s worth taking seriously.
Types of anxiety disorders in children and teens
Anxiety can show up in different patterns depending on age, temperament, and life circumstances. Common types include:
- Generalized anxiety disorder (GAD)
- Social anxiety disorder
- Panic disorder
- Separation anxiety disorder
- Specific phobias
A child can also have anxiety alongside other concerns, like depression, trauma-related symptoms, ADHD, or autism spectrum traits, which can make symptoms look more complex.
Common anxiety symptoms in teens and kids
Anxiety affects both the mind and the body. Some kids describe anxiety clearly (“I can’t stop worrying”), but many don’t have the words for it. Instead, you may see behaviors and physical complaints.
Emotional and behavioral signs
- Frequent worry, “what if” thinking, or reassurance-seeking
- Irritability, anger, or being “on edge” (especially in teens)
- Avoidance (school refusal, skipping activities, avoiding friends)
- Trouble concentrating or making decisions
- Restlessness, pacing, fidgeting, or difficulty relaxing
- Increased clinginess (often more common in younger kids)
Physical anxiety symptoms
Parents are often surprised by how strongly anxiety can affect the body. Common physical anxiety symptoms can include:
- Stomachaches, nausea, or changes in bathroom habits
- Headaches or muscle tension
- Fatigue, low energy, or feeling “wiped out”
- Racing heart, shortness of breath, dizziness, or chest tightness
- Trouble falling asleep, frequent waking, or nightmares
Anxiety can look different in teen girls and teen boys
Anxiety symptoms in a teenage girl may show up as perfectionism, social anxiety, body-image distress, sleep disruption, or stress spikes around menstruation.
Anxiety symptoms in a teenage boy may look like irritability, anger, withdrawal, refusal to talk about worries, or acting “fine” while avoiding school or friends.
“Weird” anxiety symptoms families sometimes miss
What symptoms can anxiety cause that don’t seem obvious? Some kids and teens describe feeling detached (“this doesn’t feel real”), getting sudden waves of fear, or feeling like they can’t control their thoughts. These experiences can be scary, but they can also be consistent with anxiety or panic.
What causes anxiety in teens and children?
There’s rarely one single cause. Anxiety often develops from a mix of factors, including:
- Genetics or family history
- Big transitions (moves, divorce, loss, changing schools)
- Bullying or social pressure
- Academic stress or performance pressure
- Trauma exposure or chronic stress
- Medical issues, sleep deprivation, or substance use
- Neurodevelopmental differences (like ADHD or autism)
Sometimes the “cause” is less about one event and more about a pattern: a teen feels behind socially, sleep keeps slipping, school pressure rises, and anxiety builds.
How is anxiety diagnosed & treated in teens and kids?
A diagnosis typically begins with a clinical assessment that looks at symptoms, duration, triggers, and how much anxiety is affecting daily functioning. Many providers also screen for depression, trauma-related symptoms, and attention concerns.
Treatment often includes therapy, skills practice, and family involvement. Many families start by learning about CBT for anxiety, which teaches kids and teens how to notice anxious thoughts, calm physical stress responses, and gradually face fears instead of avoiding them.
Depending on severity, a teen may benefit from weekly outpatient therapy, or a more structured program. If you’re weighing options, it can help to explore our IOP in Los Angeles, where teens can get consistent support while still living at home.
For families trying to understand higher levels of care, it can also be useful to review IOP vs residential treatment for teens, especially when symptoms are leading to school refusal, shutdown, panic, or safety concerns.
How to help a child or teen with anxiety
Support at home can make a real difference, especially when it reduces shame and increases predictability.
- Name what you’re seeing without labeling (“I’ve noticed mornings feel really hard lately.”)
- Focus on patterns, not single moments
- Keep routines steady (sleep, meals, school-day rhythm)
- Encourage small steps instead of avoidance
- Model calming tools (breathing, grounding, walking, journaling)
- Loop in school supports when anxiety affects attendance or performance
If you’re unsure where to begin or what approach fits your child’s age and needs, you may want guidance on choosing therapy for a teen, including what questions to ask and what types of support may be available.
When to get help for anxiety: Professional assistance
Consider professional help when:
- Symptoms last weeks to months and don’t ease with basic support
- Anxiety is interfering with school, sleep, friendships, or daily routines
- Your child is avoiding more and more situations
- Panic symptoms are showing up (racing heart, dizziness, fear spikes)
- You’re seeing emotional outbursts, shutdown, or persistent distress
- Social stress is escalating anxiety (including bullying or pressure to fit in)
Social dynamics can intensify anxiety quickly in adolescents. If you suspect that friend groups, social media, or fitting-in pressure is playing a role, it may help to read about peer pressure and mental health and how it can affect stress levels and decision-making.
