When a parent describes their teenager to us on a consultation call, these are the things we’re listening for. None of them require a clinical degree to answer, and together they tell you more than any online quiz.

1. How long has it been going on?

Ordinary adolescent misery moves. It arrives after a fight or a rejection or a bad grade, sits for a few days to a couple of weeks, and lifts. Depression settles in and stays. The rough working line clinicians use is two weeks of most days, but honestly, most parents who call us aren’t describing two weeks. They’re describing “since around spring break,” and they’ve been talking themselves out of it since.

If you’re having trouble dating it, that’s information too. When you genuinely cannot remember the last time your kid seemed like themselves, it’s been long enough.

2. Is it everywhere, or just at home?

This is the single most useful question and almost nobody asks it. A teenager who is flat and hostile at home but animated with friends, engaged in a sport, and functioning at school is telling you something about your house or about individuation, not about depression. That may still be worth addressing. It’s a different problem.

Depression doesn’t respect the boundary of the front door. It shows up in the group chat, at practice, in the classroom, in the parts of life your teen actually cares about. When you call the school and the counselor says they’ve noticed it too, take that seriously. When the school says the kid seems fine, that’s meaningful evidence in the other direction.

3. Have they dropped something they used to love?

Not “seems less interested.” Dropped. Quit the team. Stopped picking up the guitar. Let a friendship they’d had since fifth grade go quiet without appearing to notice.

Adolescents change interests constantly, so this one takes some judgment. The distinction is whether something replaced it. A kid who quits soccer for theater is fifteen. A kid who quits soccer for their bedroom is worth a conversation.

4. Is anything getting worse rather than staying flat?

A rough patch tends to plateau. Depression tends to compound, because its symptoms feed each other. Sleep goes, which makes the mood worse, which makes school harder, which makes the shame worse, which takes out more sleep. If you chart the last three months and the line points down instead of sideways, that trajectory matters more than where the line currently sits.

Parents arrive at the word “depressed” because it’s the word available. It’s frequently not the most accurate one.

A teenager running high anxiety often presents as shut down. Avoidance looks like laziness. Exhaustion from a nervous system that never fully powers down looks like apathy. Refusing to go places looks like sulking. From the outside, a chronically anxious sixteen-year-old and a depressed sixteen-year-old can be nearly indistinguishable, and they need different work.

Trauma responses do the same thing. A teenager who went through something they haven’t told you about can go flat, lose interest, stop sleeping, and get irritable. That’s a nervous system stuck in a protective mode, not a mood disorder, and treating it as a mood disorder is how families spend two years in therapy that doesn’t move.

ADHD is the other frequent confusion, particularly in girls, who often get identified late. Years of falling behind and not knowing why produces a demoralization that reads exactly like depression by the time anyone is looking.

This is the practical reason to get an assessment rather than self-diagnose from a symptom list. The behaviors overlap almost completely. What’s driving them does not, and what’s driving them determines what actually helps.

Write down dates, not impressions

Memory is unreliable and anxious memory is worse. For two weeks, note what you actually observed and when. Not “seemed down.” What time they got up, whether they ate, whether they left the house, whether they spoke to anyone. Parents are consistently surprised by what the notes show, in both directions. Some find the pattern is milder than it felt. Others realize their kid hasn’t left the house socially in five weeks.

Ask the school

A counselor or a teacher your teen likes sees them in a setting you never do. One email answers question two, the everywhere-or-just-home question, better than a month of guessing.

Describe, don’t diagnose

When you do raise it, say what you observed. “You’ve been sleeping a lot and I haven’t seen Marcus around in a while” is hard to argue with. “I think you’re depressed” is a diagnosis from someone not qualified to make one, and your teen will hear it exactly that way.

You can go first, by yourself

You do not need your teenager’s agreement to get a professional opinion on what you’re seeing. Parents book consultations with us on their own regularly, describe the last few months, and leave with a clearer sense of whether this needs treatment or watching. Plenty of teens agree to come later, after their parent went first and it turned out to be survivable.
