5 Signs of Red Flag Teen Behaviors and How to Be There for Them

Being a teen isn’t easy and neither is parenting or supporting one. Between school, friends, growing up, and figuring out who they are, teens can go through a lot. Sometimes, though, changes in their behavior can be more than just a rough day or a bad mood. That’s when we need to pay attention.

Here are 5 signs of red flag behaviors in teens and what you can do to help.

 
Increased Anger or Irritability

Sure, everyone gets frustrated sometimes. But if your teen is snapping at you constantly, yelling over small things, or seems angry all the time, it could be more than just typical teen moodiness. This kind of behavior might mean they’re struggling with emotions they don’t know how to handle.

 

How to help: Instead of yelling back, try calmly asking what’s really going on. Say something like, “I’ve noticed you seem upset a lot lately. I’m here if you want to talk.”

 
Loss of Interest

Teens want more independence—it’s normal. But if they’re completely withdrawing, staying locked in their room for hours, avoiding friends, or no longer doing things they used to enjoy, this could be a sign of depression or anxiety.

 

Helpful tip: Don’t force them to talk right away. Just let them know you’ve noticed the change and that you care. A simple, “I miss seeing you smile. You don’t have to go through things alone,” can open the door.

 
Academic Struggles

School struggles happen, but if a teen who normally does okay is suddenly failing or skipping school, something deeper might be going on—like stress, bullying, or feeling overwhelmed.

 

What to do: Ask with kindness, not judgment. Try, “School seems tough right now. Want to talk about what’s making it hard?” Show support, not pressure.

 
Risky Behavior

If you notice risky behavior (like sneaking out, using drugs or alcohol, or talking about self-harm) it’s important to take it seriously. These choices can be signs they’re trying to cope with something painful.

How you can help: Stay calm and get help. Reach out to a trusted adult, school counselor, or mental health professional. It’s okay not to have all the answers—but it’s not okay to ignore the signs.

 
Hopelessness 

If your teen says things like “I don’t care anymore,” “Nothing matters,” or even jokes about not wanting to be here—listen. These are red flags for depression and need attention right away.

Let them know you hear them. Say, “That sounds really heavy, and I’m so sorry you feel that way. You’re not alone, and I want to help you find someone to talk to.” Then reach out to a professional right away.
