Your teen used to talk your ear off at dinner. Now they come home, go straight to their room and answer every question with "fine." Is this normal teenage moodiness, or something more? It can be hard to tell, and many parents worry about overreacting or missing something. This guide explains how depression in teens often shows up, what can cause it, how it differs from everyday ups and downs, and when to get help.
If you are worried about your teen's safety right now, don't wait. Call or text 9-8-8 at any hour, or call 911 if they are in immediate danger. More crisis numbers are listed near the end of this article.
Moodiness or depression?
The teen years bring big changes in the body, the brain, friendships and school. Some moodiness is part of growing up. A teen who is grumpy after a bad day, or sad for a few days after a breakup, is usually coping in a normal way.
Depression is different. It lasts longer, it shows up in more parts of life and it gets in the way of daily living. A helpful rule of thumb: if the change in your teen has lasted two weeks or more, shows up most days and is affecting school, friends or family life, it's time to take a closer look.
Signs of depression in teens
Depression doesn't always look like sadness, especially in teens. Many teens with depression seem more irritable or angry than sad. Watch for changes like these:
Feeling sad, empty, hopeless or worthless much of the time
Getting easily frustrated, snapping or having angry outbursts
Losing interest in sports, hobbies or friends they used to enjoy
Pulling away from family and spending much more time alone
Sleeping a lot more or a lot less than usual
Eating a lot more or a lot less
Seeming tired all the time or low on energy
Trouble focusing, remembering things or making decisions
Grades dropping or skipping school
Frequent headaches or stomach aches with no clear cause
Talking about being a burden, or about death or suicide
Your teen may have only a few of these signs. What matters most is the change from how they usually are.
What causes depression in teens?
There is usually no single cause. Depression tends to come from a mix of things that build up over time. These can include:
Family history. Depression can run in families.
Stress and pressure. School, sports, jobs and plans for the future can pile up.
Loss and big changes. A death, a move, a family separation or a breakup can hit hard.
Bullying and friendship problems. This includes what happens online.
Hard experiences. Trauma, abuse or discrimination can have a lasting effect.
Other struggles. Anxiety, ADHD, learning challenges, questions about identity or ongoing health issues can add to the load.
Sleep. Many teens don't get enough, and poor sleep and low mood often feed each other.
Phones and social media are part of this picture for many families. They can be a source of connection and a source of stress. Our article on screen time and teen mental health looks at both sides.
None of this means you did something wrong. Depression can affect teens from loving, caring homes.
How to talk with your teen
Starting the conversation is often the hardest part. A few things can make it easier.
Pick a low-pressure moment. Car rides, walks or cooking together can feel less intense than a sit-down talk.
Say what you've noticed, without judging. "You've seemed really tired and quiet lately. I'm wondering how you're doing."
Listen more than you talk. Try not to fix, lecture or argue. Let them finish.
Take their feelings seriously. Avoid phrases like "you have nothing to be sad about." To your teen, the feelings are very real.
Keep the door open. If they shut down, that's okay. Let them know you'll check in again, and do.
If your teen won't talk to you, that doesn't mean they won't talk to anyone. Many teens find it easier to open up to a therapist than to a parent.
When to get help
Reach out for professional support if:
The changes have lasted two weeks or more
Your teen's mood is affecting school, friendships or family life
They have stopped doing things they used to love
They are using alcohol, drugs or self-harm to cope
You have a gut feeling that something is wrong
Trust your instincts. You don't need to be sure it's depression before you ask for help. A therapist can help sort out what's going on.
Warning signs that need action now
Some signs mean your teen may be thinking about suicide. These include talking about wanting to die, giving away belongings, saying goodbye, looking up ways to die or a sudden calm after a long period of distress. Take any of these seriously.
It's okay to ask your teen directly, "Are you thinking about suicide?" Asking does not put the idea in their head. For a full guide, read our article on teen suicide warning signs.
How therapy helps teens with depression
Depression is treatable, and many teens start to feel better with the right support. In therapy, a teen can:
Understand what they are feeling and why
Learn skills to handle hard thoughts and emotions
Build routines around sleep, activity and connection
Work through stress, loss or conflict
Rebuild confidence at school and with friends
Therapists often use approaches like cognitive behavioural therapy (CBT), which looks at the link between thoughts, feelings and actions. Parents may be invited to join some sessions, or to meet with the therapist on their own for guidance. At the start, the therapist will explain how privacy works for your teen and when safety concerns would be shared.
If an assessment or diagnosis would help, our psychologists can assess, and our nurse practitioners can diagnose and talk with you about whether medication might be part of the plan.
Small things that help at home
Therapy is important, but everyday life at home matters too. While you arrange support, these small steps can help.
Protect sleep. A regular bedtime and wake-up time, even on weekends, can make a real difference to mood.
Get moving together. A short walk, a bike ride or shooting hoops counts. Invite, don't force.
Keep some routine. Regular meals and a predictable week give a struggling teen something steady to lean on.
Spend easy time together. Watching a show or cooking side by side can keep you connected without pressure to talk.
Go easy on school pressure for now. Talk with your teen about what feels doable, and adjust expectations while they recover.
Looking after yourself too
Watching your child struggle is exhausting. You might feel scared, guilty or worn out. Those feelings are normal, and you deserve support as well. Many parents find it helps to talk with a therapist of their own while their teen is in treatment.

Frequently asked questions
Will my teen grow out of it?
Some low moods pass on their own, but depression often doesn't. Getting help early means your teen doesn't have to struggle alone, and they can learn skills they'll use for life.
What if my teen refuses therapy?
That's common. Try offering a single session to "see what it's like," or let them help choose the therapist. You can also start by meeting with a therapist yourself for guidance.
