"He's just being a teenager." Sometimes that is exactly right. Adolescence genuinely does involve mood swings, withdrawal, irritability and a strong preference for a closed bedroom door. The difficulty for parents is that depression in teenagers looks, at first glance, almost identical.
The question is not intensity. It is duration and function.
A bad week after a break-up is ordinary. Two months of flatness is not. The single most useful thing you can ask yourself is: has this changed what my child is able to do? Ordinary moodiness does not usually stop a teenager from seeing their friends, keeping up at school, or enjoying the things they have always enjoyed. Depression does.
Signs that deserve attention
- Withdrawal from friends they previously chose to spend time with
- A drop in school performance that is not explained by anything else
- Sleeping far more or far less, consistently, for weeks
- Irritability that is new — in teenagers depression often looks like anger, not sadness
- Any talk of self-harm, hopelessness, or being a burden — this is never "just a phase"
What not to do
Do not lead with a solution. "Have you tried going for a walk?" lands as dismissal, however kindly meant. Start by asking, and then genuinely listening to the answer without rushing to fix it. You are not trying to diagnose your own child — you are trying to keep the door open.
Coming in
A first consultation for an adolescent is mostly conversation. There is no test, no label handed out on day one, and in a great many cases no medication. Bringing your child in early is not an overreaction; it is the cheapest, easiest point at which to help.
