How do I tell depression from normal teenage moodiness?

Look at duration, breadth and function. Ordinary moodiness fluctuates and lifts around good things; depression persists for weeks, shows up across home, school and friendships, and takes the pleasure out of things that used to work.

Will asking about suicide put the idea in their head?

No. Research consistently finds that asking directly does not increase risk and often reduces distress. Ask plainly, without flinching, and stay steady when they answer.

They refuse to see anyone. What now?

Go yourself first — parent-only sessions are useful and reduce the threshold. Offer a choice of format rather than a choice of whether: GP, school counsellor, or an online option.

Should I take their phone away?

Not as a first move. For a withdrawn teenager the phone is often the last remaining social thread. Work on sleep and night-time use before you touch daytime access.

Quieter Than Usual: Recognising Depression in Teenagers

Teenage depression rarely announces itself as sadness. More often it arrives as irritability, exhaustion and a slow withdrawal that looks, from the outside, like an ordinary phase.

What depression looks like at fifteen

01
Irritability rather than sadness
Snapping, contempt and a short fuse are more typical presentations in adolescents than tearfulness.
02
Anhedonia
The clinical heart of it. Things that used to be enjoyable stop delivering anything — and this is the sign parents most reliably notice in hindsight.
03
Physical complaints
Headaches, stomach pain, exhaustion that sleep does not touch, appetite that changes in either direction.
04
Withdrawal that widens
First from family, then friends, then the activities. The order matters less than the direction of travel.
05
Self-criticism
Language shifts from "I did badly" to "I'm useless". Global, permanent, personal — that triad is worth taking seriously.

The first conversation

Research highlight

Epidemiological and clinical research on adolescent depression describes a presentation that differs from the adult picture: irritable mood is recognised as a diagnostic equivalent of depressed mood in young people, and somatic symptoms and social withdrawal are common. Studies examining the safety of screening find that asking adolescents directly about suicidal thoughts does not induce distress or increase ideation, and may reduce it; delay in identification, by contrast, is associated with longer episodes and greater functional impairment.

“Depression in a teenager is not usually a storm. It is a light going down slowly enough that everyone's eyes adjust.”
Sian Trombley

What helps while you wait for help

Protect sleep timing above almost everything else; it is both a symptom and a driver.
Keep one daily contact ritual that requires nothing of them emotionally.
Reduce demands temporarily rather than removing structure entirely.
Get outside once a day, even briefly, even badly.
Tell them plainly that this is treatable and that you are not frightened of them.

When to act immediately

Seek urgent help — your GP, NHS 111, or emergency services — if your child has a plan or intent to harm themselves, has recently self-harmed, is expressing hopelessness about the future, or has withdrawn abruptly after a period of distress. Do not wait for an appointment window, and do not manage this alone.

Teenage depression is often not sadness. It is a slow narrowing of everything that used to be worth doing.

What you can try this week

Step 01

Take the pressure off eye contact

Car journeys, walks and washing up produce far more disclosure than a face-to-face conversation on the sofa. Side by side lowers the stakes.

Step 02

Ask one plain question

"You've seemed heavier lately. Not in trouble — I just want to know how bad it's been." Then leave a long silence.

Step 03

Protect one small anchor

One walk, one meal at the table, one thing they used to like. Behavioural activation is slow, unglamorous and genuinely effective.

Key takeaways

Irritability is a more common presentation than sadness in adolescents.
Loss of interest in previously enjoyed things is the signal that matters most.
Two weeks of persistent change across several areas is the practical threshold.
Asking directly about self-harm or suicidal thoughts does not increase risk.
Treatment works, and early treatment works better.

Reflection

When did I last see my child properly enjoy something?
Am I calling this a phase because it is one, or because I want it to be?
What would I need in place to be able to ask the hardest question calmly?
