5 Signs Your Teen May Be Struggling With Anxiety

Anxiety in teenagers doesn't always look the way we picture it. It's not always panic attacks or a fear of leaving the house. Often, it's quieter, and easier to miss.

After more than 20 years working with young people and families in human services, I've seen how often teen anxiety gets misread as attitude, laziness, or "just a phase." The stakes of missing it are real. So here are five signs worth paying attention to.

1. Avoidance That Looks Like Defiance

When a teen refuses to go to school, won't attend family events, or suddenly stops doing things they used to enjoy, it can feel like they're being difficult. More often, they're avoiding something that feels genuinely threatening to them, even if that threat is invisible to everyone else.

Anxiety creates avoidance. And avoidance, when it works (the thing they feared doesn't happen because they escaped it), gets reinforced. The cycle builds.

2. Physical Complaints With No Clear Medical Cause

Headaches before school. Stomachaches on weekdays. Feeling sick when something stressful is coming up. The body and the mind aren't separate systems, and teens often express emotional distress through physical symptoms before they can name what they're feeling.

This doesn't mean the pain isn't real. It absolutely is. But if medical causes have been ruled out, anxiety is often part of the picture.

3. Irritability and Emotional Reactivity

Anxiety is exhausting. When a young person is spending enormous internal energy managing fear, worry, or dread, their capacity for everyday frustration narrows significantly. Small things become big things. Reactions that seem outsized often aren't. They're the overflow from a system that's already running at capacity.

4. Difficulty Sleeping or Constant Fatigue

Anxious minds don't shut off at bedtime. Racing thoughts, worry spirals, and the body's ongoing stress response make falling asleep and staying asleep genuinely hard. The resulting exhaustion feeds back into everything else: mood, concentration, motivation, social functioning.

5. Reassurance-Seeking That Never Quite Lands

Does your teen repeatedly ask "are you sure everything's okay?" or need to go over the same worries again and again, even after you've answered them? That loop is a hallmark of anxiety. Reassurance provides brief relief but doesn't resolve the underlying fear, and over time, the need for it increases.

What to Do With This

Recognizing the signs is the first step. The next is finding the right language to open a conversation, without your teen feeling interrogated, diagnosed, or like they've done something wrong.

That's exactly what I wrote about in When Anxiety Takes Over, a workbook designed to help teens understand their own anxiety in language that makes sense to them, with tools they can actually use.

"The goal isn't to fix your teen's anxiety for them. It's to help them build the capacity to navigate it themselves."
