Mental health in the teenage years

Three Wednesdays in a row, your daughter has come home from school, gone straight to her room, and stayed there till morning. She's eaten dinner alone. Her grades haven't dropped. She's not visibly upset. She's just quieter, smaller, more inside herself.

You've been wondering whether to say something for two weeks.

This article is about that wondering. The mental health of teenagers, in two-home families, is a wide territory. It includes the everyday low moods that pass on their own. It includes the longer patterns that quietly erode a teen over months. It includes the acute crises that need professional help today. And it includes everything in between.

Most parents, at some point in the teen years, will be in the wondering. Most teens will pass through some version of mental-health difficulty. Most families will, somehow, find their way through it. The work, for the parents, is partly to recognise what they're seeing, partly to know when to act, and partly to hold the family steady while the teen finds their way back to themselves.

This is one of the harder articles in this module. It's also one of the more useful. We'll cover what's normal, what isn't, what to do when you're not sure, and how two parents in two homes can support a teen whose mental health needs attention.

A note before we go further. This article is not a clinical manual. It's a starting point for a parent who's noticing something. If you have any concern that your teen is in serious distress or at risk, contact a professional today. The school counsellor, the GP, a child and adolescent psychologist, or a national mental-health helpline. Parents don't manage these things alone, and they shouldn't.

The frame

Teenage mental health, as a general topic, has three things to know.

It's common. A meaningful proportion of teenagers in any given year experience anxiety, low mood, periods of significant distress, or other mental-health difficulties. The rates have risen over the last decade. If your teen is struggling, they're not unusual. Nor are you.

It's treatable. Most teen mental-health difficulties respond well to early support. School counsellors, therapists, family doctors, and child psychologists have a real toolkit. The earlier the support, the better the trajectory.

And it's serious. Treatable doesn't mean trivial. Teen mental health, when it goes badly, can have severe consequences. Don't underweight what you're seeing because all teenagers go through this. Some teens go through more than they can handle.

Hold all three at once. Common, treatable, serious. None of them on their own gives you the right response.

Why the teen years are particularly vulnerable

A short biological note, because it helps to understand what's happening.

The teenage brain is undergoing rapid change. The emotional centres develop earlier than the regulation centres. This means teenagers experience emotions intensely while still building the capacity to manage them. This is normal neurological development, not weakness or failure.

Add to this: hormonal changes, sleep-cycle shifts, social-life intensities, identity questions, academic pressure, the saturation of the phone, and (in the families this library is written for) the work of living across two homes. The teenage years are a period of high emotional load on a brain that's still figuring out how to carry it.

This isn't a reason to lower the bar on what you notice. It's a reason to be patient with what you see. Some of what looks like mental health is actually being a teenager. Some of what looks like being a teenager is actually mental health needing attention. The work is to tell the difference, and to be willing to act when you can't.

The signs that aren't dramatic but matter

Most parental noticing is in the quiet end. Not a crisis. Not a drama. A change.

Some of the patterns that, on their own or together, suggest something is happening.

A persistent shift in mood. Not a bad week. A few weeks. They're flatter, sadder, angrier, more anxious than their baseline. The change is sustained.

Withdrawal from things they usually enjoy. They've stopped drawing, stopped playing music, stopped going to the friend group, stopped the small everyday rituals that used to anchor them.

Sleep changes. They're sleeping much more than usual, or much less. They're awake at 3am. They can't get up in the morning. Their phone's been on at 2am for several nights running.

Appetite or eating changes. Eating less, eating more, eating in patterns that have shifted, secrecy around food, weight changes you can see.

A drop in school performance, or a striking surge of perfectionism. Either tail can be a signal.

Increased irritability or low frustration tolerance. Small things now produce big reactions. They snap at younger siblings. They walk out of conversations.

Disengagement from self-care. Not showering. Not changing clothes. The body has stopped being something they look after.

A withdrawal of language. They give one-word answers. They stop telling you about their day. They stop telling you anything.

Statements that are more than the moment. I'm such a failure. I hate myself. I don't see the point. These are not always alarms; sometimes they're a teen trying out language for what they feel. But they're worth attending to.

Physical complaints with no clear cause. Persistent headaches, stomach aches, fatigue. The body sometimes carries what the mind hasn't put into words yet.

None of these alone is a diagnosis. Several of them together, persisting for more than a few weeks, is a signal that something is happening and the family should pay attention.

The signs that need urgent action

A separate, shorter list. These need a response today, not next week.

• The teen describes wanting to die, wanting to disappear, or talks about ending their life.
• The teen describes a plan to harm themselves.
• You see signs of self-harm.
• The teen has stopped eating substantially, or has rapid significant weight changes.
• The teen has had a serious change after a specific event (assault, bullying, a major rupture, a serious incident at one of the homes).
• The teen has substantially withdrawn from all of life.
• You're afraid of what they might do.

If you're seeing any of these, contact a professional today. The GP. The school counsellor. A child and adolescent psychiatrist if you have access. A crisis helpline if you cannot reach a professional in time.

Modules 17, 18, and 19 of this library go into specific responses for self-harm, eating disorders, and acute crisis. If you're recognising signs in any of those areas, those modules are written for you.

What to do when you notice something

Most parents, when they notice something, hesitate. They don't want to overreact. They don't want to underreact. They don't want to embarrass the teen by naming it. They don't want to leave it alone if it's serious.

Some patterns that help.

Pay attention without watching. Teens know when they're being observed. If you start scrutinising, they become more guarded, not more open. Pay attention in the way you'd pay attention to a friend going through something. Quiet, present, unflashy.

Make space for the conversation, not the interrogation. The car ride. The kitchen at a quiet moment. A walk. A meal that's not heavy with expectation. I've noticed you've been quieter lately. Anything you want to talk about? Then wait. Don't fill the silence.

Don't lead with solutions. Have you tried going for walks. Have you talked to your friends. Have you tried listening to different music. The teen doesn't want a checklist. They want to be heard first. The solutions, if useful, can come later.

Listen to what they say without rushing to reassure. Mum, I just feel really empty all the time. The instinct is oh sweetheart, you'll feel better, this is just a phase. The better move is that sounds really hard. Tell me more about the empty feeling. Reassurance, given too quickly, signals that you don't want to hear about it.

Don't take it as your failure. If your teen is struggling, it's not because you've failed. Mental-health difficulties happen to teens whose parents do everything well. Don't centre yourself in what they're going through.

Trust your gut, even if you're not sure what you're seeing. Most parents, in retrospect, knew something was wrong before they could name it. If you're worried, ask. Even if it turns out to be nothing serious, you've practised the conversation, and the teen knows the door is open.

The Co-Parent dimension

Mental-health difficulties are one of the things that absolutely require both parents to be in the loop. This isn't a privacy-vs-safety question. The teen needs both homes to be alert.

Some patterns help.

Tell the Co-Parent what you're noticing. Not as a complaint. As information. Hey, I've been wondering about Lily. She's been quieter the last few weeks. Have you noticed anything at yours? The Co-Parent might have noticed the same thing. They might have noticed something different. Together you have a fuller picture.

Compare notes regularly. A short check-in every couple of weeks. How's she been at yours? Any sleep issues? Any change in mood? This isn't surveillance; it's coordination.

Don't compete on who's more concerned. One parent is sometimes quicker to worry; the other quicker to dismiss. The two of you need to find a middle that's neither catastrophising nor minimising. Let's both watch and check in next week.

Agree on the threshold for action. What patterns or signs would prompt you to bring in a professional. Discuss this together so you're not deciding under pressure. If she's still like this in two weeks, let's call the GP.

Coordinate when you do bring in help. If you're starting therapy, both parents should know. If the GP visit happens, both parents should know what was said. The teen's medical and mental-health care is a shared parental responsibility, even when the day-to-day care is split across two houses.

Don't let the mental-health concern become a competition for the teen. If the teen is struggling, both homes need to be safe places. Don't position one home as the better one for the teen's mental health. Both need to be steady.

When you have different views on what's happening. Sometimes one parent thinks something is serious and the other doesn't. The way through is usually a third opinion. The school counsellor, the GP, a family therapist. Bring someone neutral in. Don't let the disagreement between parents become its own stress for the teen.

What to say to your teen

Some things that help, when you're having the conversation.

I've noticed you've been struggling. I'm not asking you to explain it. I'm just letting you know I see you.

You don't have to be okay all the time. I'd rather you tell me when you're not.

I can't always understand exactly what you're going through. But I can be here. And I can help you find someone who does understand it.

Mum and I are both here. You don't have to choose who to talk to. You can talk to either of us, both of us, or neither, and we'll still be on your side.

If it ever gets to a point where you feel you can't stay safe, I want you to call me. Even at 3am. Even if you think I'll be angry. Even if you've done something you wish you hadn't. I'd rather know than not.

Some things that don't help.

Cheer up. Snap out of it. Other people have it worse. When I was your age. You're being dramatic. This is just teenage hormones. You'll grow out of it. These minimise. They teach the teen that you're not the person to bring this to.

When professional help is needed

Most parents, at some point, will need to bring in someone outside the family.

Some markers for when to do this.

• The signs you're seeing have persisted for more than a few weeks despite your support.
• The teen has asked for help.
• The teen has named something specific (anxiety, depression, panic attacks, intrusive thoughts).
• You are seeing any of the urgent signs from earlier in this article.
• The Co-Parent thinks help is needed.
• The school has flagged a concern.
• You're spending mental energy you don't have on managing it on your own.

The first port of call is usually the GP, the school counsellor, or a child and adolescent psychologist. Different countries and regions have different pathways. Whatever's available locally, use it. Don't try to handle clinical-level concerns at the kitchen table.

The teen may resist. I don't need to see anyone. I don't want to talk about it. This is normal. Often the first session is the hardest, and the teen finds that having a third party (someone neither parent) makes some things easier to say. Encourage. Don't push too hard. Sometimes a let's just go once and see lowers the threshold.

When you, the parent, also need support

A short note.

If your teen is going through a serious mental-health period, you're carrying a lot. The worry is heavy. The not-knowing is heavy. The split between home and second home, with all its coordination and information sharing, is heavy. Don't carry it alone.

Speak to your own GP. Your own therapist if you have one. A friend who's been through similar. The school counsellor as a sounding board for parents, not just teens. Other parents in two-home families, if you have a network.

Your wellbeing matters in itself. It also matters because your teen needs you to be steady. The parent who's running on empty cannot hold the teen who's running on empty. Look after yourself as part of looking after them.

The longer arc

A reminder that helps in the harder weeks.

Most teen mental-health difficulties pass. Some pass quickly with light support. Some pass slowly with substantial support. Some leave the teen with patterns they'll carry into adulthood, where they continue to be addressed in different ways. Very few are permanent in their early teen form.

The 14-year-old who's not okay this year may, at 17, be a different teen. The 16-year-old who's been struggling for a long time may, at 22, be doing well. The relationship you build with them through these years is what they'll remember as much as the difficulty itself.

Don't measure yourself by whether you fixed it. Measure yourself by whether you stayed close, paid attention, brought in help, kept showing up.

The landing

Wednesday evening, the third week.

You go up. You knock. Can I come in?

She nods.

You sit on the end of her bed. You don't have a plan for what to say. You let the silence hold for a minute.

I've been thinking about you. Wanting to check in. You don't have to talk about anything. I just wanted to be in the room with you for a bit.

She doesn't say anything for a while. Then: I don't know what's wrong. Just everything feels heavy.

You nod. You don't try to make it lighter.

That sounds really hard.

You sit with her. You don't ask any more questions. After a while you say: Whatever this is, I'm here. Mum's here. We're going to figure out what helps. We don't have to figure it out tonight.

She nods. You sit a bit longer. Then you go.

Later that night you message the Co-Parent. I sat with Lily tonight. She said everything feels heavy. I didn't push. I want to talk to you about getting her in to see someone. Can we chat tomorrow?

The Co-Parent replies. Yes. Glad you went up. I've been worried too. Tomorrow morning. We'll figure it out.

That's the work. Two parents, in two homes, paying attention to a teen who's not okay. Not panicking. Not minimising. Stepping in. Bringing in help. Holding the family steady while the teen finds their way through.

Most teens find their way. Many of them, looking back from their twenties, will say it was the steadiness of the adults around them, more than any single intervention, that made the difference.

Be that steadiness. With the Co-Parent. For the teen. Through whatever this season turns out to be.
