Your 15-year-old has been in their room for most of a month. Dinner is one-word answers. The friend who used to be here every Saturday hasn’t come by since August. Grades slipped a letter.
And every adult you ask says the same thing: that’s just being a teenager.
Maybe. Adolescence genuinely includes moodiness, privacy, slammed doors and a few terrible weeks that pass on their own. Treating every hard stretch as an emergency isn’t good for anyone, least of all the teenager. But “it’s just a phase” has also kept a lot of families from asking a question they should have asked months earlier.
There’s a better way to sort this than guessing, and it comes from the National Institute of Mental Health. It’s not a diagnosis. It’s a threshold for picking up the phone, and it’s short enough to remember at 2 a.m.
If you need help today
Some situations don’t wait for an appointment.
Call or text 988 to reach the 988 Suicide & Crisis Lifeline. You can also chat at 988lifeline.org. It’s free, confidential and staffed around the clock, every day of the year. It’s not only for the person in crisis. Parents, friends and anyone worried about someone else can use it too.
Call 911 for a life-threatening situation.
NIMH’s instruction is direct: if a young person’s behavior is unsafe, or they talk about hurting themselves or someone else, seek help immediately. Not after the weekend. Not after you’ve thought about it.
Asking a teenager directly whether they’re thinking about suicide does not plant the idea. It gives them a chance to answer, and many are relieved someone finally asked.
The three-part test that does most of the work
NIMH’s guidance for parents, published as Children and Mental Health: Is This Just a Stage?, sets out when to seek an evaluation. Three conditions, and any one of them is enough to make the call.
It has lasted weeks or longer. Not a bad Tuesday. Not a rough stretch after a breakup that’s already easing. Weeks of the same thing.
It’s causing distress for the young person or for the family. Real suffering, not inconvenience.
It’s interfering with life at school, at home, or with friends. This is the one most parents can measure. Did they drop the team? Have they stopped answering friends? Are they missing school days they didn’t used to miss?
Hold that up against the scenario at the top. A month of withdrawal, a friend who has disappeared from the house, grades sliding. That’s duration plus interference. Under NIMH’s own threshold, that’s a call to the pediatrician, not a wait-and-see.
Notice what the test does not require. It doesn’t ask you to decide whether this is depression or anxiety or something else. It doesn’t ask you to be sure. Sorting out what’s going on is the clinician’s job. Yours is noticing the pattern and acting on it.
How common this is, in numbers
If part of what’s stopping you is the feeling that your family is an outlier, the federal data says otherwise.
CDC reports that among teenagers aged 12 to 17 surveyed between 2021 and 2023 in the National Health Interview Survey-Teen, 20% had symptoms of anxiety in the previous two weeks and 18% had symptoms of depression. Among children and teens aged 3 to 17 in the 2023 to 2024 National Survey of Children’s Health, 11% had a diagnosed anxiety condition, 8% a behavior disorder and 4% depression.
The Youth Risk Behavior Survey, which asks high school students directly, found in 2023 that 40% had felt persistently sad or hopeless during the past year, and 20% had seriously considered suicide. These are the numbers that make adults go quiet. They are also the reason the 988 line exists and why pediatricians now ask about mood as a matter of routine.
One more figure, from the same CDC collection, and it’s the one worth posting on the refrigerator: 20% of teenagers aged 12 to 17 had an unmet mental health care need. Not “didn’t need help.” Needed it and didn’t get it. Access is a real obstacle, and knowing that in advance changes how you approach the search.
Changes worth paying attention to
NIMH lists the signs that warrant evaluation in older children and teens. Below, those signs are regrouped by how a parent encounters them, because that’s not the order they arrive in.
Things that go quiet. Interest in activities they used to care about drains away. Energy drops. They spend more and more time alone, pulling back from friends and family. These are the easiest to miss, because nothing dramatic happens. A kid who stops doing things looks, from the outside, like a kid who is fine and just busy.
Things that change shape. Sleep shifts, in either direction: much more, much less, or sleepy all day no matter the hours. Eating changes. Exercise becomes rigid or excessive, or food and exercise start to carry a weight they didn’t before. Changes in eating and exercise can be the leading edge of an eating disorder, which this library covers in its article on body image and young people. The National Alliance for Eating Disorders runs a free helpline staffed by licensed therapists at 1-866-662-1235, 9 a.m. to 7 p.m. ET, Monday through Friday.
Sleep deserves a note of its own. It changes in almost every adolescent mental health condition, and it also changes for ordinary developmental reasons during these years. This library’s article on teen sleep explains why a later bedtime by itself is usually biology, not a symptom.
Things that are new and out of character. Smoking, drinking or drug use. Risky or destructive behavior, alone or with friends. Stretches of unusually high energy paired with needing far less sleep than normal, which is different from a teenager who stays up late and crashes.
Things that get a response the same day. Hurting themselves on purpose. Talking about suicide, in any form, including offhand. Saying they believe someone is controlling their mind, or hearing voices other people can’t hear. These are not wait-and-watch items. They go to a clinician or to 988 now.
No item on this list proves anything by itself. A teenager who sleeps more in the spring is not a case. Several of these together, persisting for weeks, interfering with their life: that’s the pattern.
How to start the conversation without running an interrogation
Most parents open with a question that cannot be answered. “What’s wrong?” invites “nothing,” and then you’ve both lost.
A few things that work better:
- Name what you’ve seen, not what you’ve concluded. “You haven’t had Maya over since school started, and you used to see her every weekend.” Observable, hard to argue with, not an accusation.
- Pick a side-by-side setting. Driving, walking the dog, doing dishes. Eye contact raises the stakes. A windshield lowers them.
- Leave silence alone. Count to ten before filling it. Teenagers often answer in the gap adults rush to close.
- Don’t fix the first thing they say. If they mention something small, resist solving it. Solving ends the conversation. Asking one more question continues it.
- Say the hard question plainly if it applies. “Have you been thinking about hurting yourself?” Calm voice, straight question, then wait.
- Tell them what happens next. Teenagers often refuse help because they imagine being hospitalized or losing all privacy. Saying “we’d start by talking to Dr. Patel, and you’d be in the room” removes a fear you didn’t know was there.
If they shut it down, you haven’t failed. Say you’ll ask again, and then ask again in a few days.
What happens when you ask for help
The path is more ordinary than most families expect.
Start with the pediatrician. NIMH advises talking to your child’s health care provider and asking for a referral to a mental health professional experienced with children. The pediatrician is also the person who can rule out physical causes for fatigue or sleep changes, which is worth doing.
Routine screening is now standard practice at that age. The US Preventive Services Task Force recommended in October 2022 that adolescents aged 12 to 18 be screened for major depressive disorder, a Grade B recommendation, meaning the Task Force found at least moderate net benefit. The same statement concluded the evidence was insufficient to judge screening for suicide risk in children and adolescents, and insufficient for depression screening in children 11 and under. That is a gap in the research, not permission to skip a concern you already have.
Gather outside observers. NIMH suggests talking with the people who see your child regularly, especially teachers. A teacher may have noticed the withdrawal in September that you noticed in October.
Expect a comprehensive evaluation, not a quick label. NIMH describes what one usually involves: an interview with parents covering developmental history, temperament, relationships, medical history and interests; information from the school such as test scores and behavior reports; and, when needed, an interview with the young person plus testing and direct observation. It takes more than one appointment. That’s a feature.
Questions worth asking before you commit to a provider
NIMH suggests asking prospective providers about their approach. Here is a version organized by what each answer tells you:
- “Is this treatment supported by research for this age group?” Evidence-based approaches exist for adolescent anxiety and depression. A provider should be able to name theirs without hesitating.
- “How are parents involved, and how much will I know?” Confidentiality shifts in adolescence. Better to understand the boundaries at the start than to collide with them in month three.
- “What should change, and how soon will we see it?” Ask for the specific measure. “She seems better” is not a measure.
- “How long do you expect this to last?” Open-ended treatment with no checkpoint is worth questioning.
- “What is there to do between sessions?” Much of what works in adolescent therapy happens outside the room.
Ask the school what it can do. NIMH points families toward school accommodations when emotional or behavioral difficulties are getting in the way of learning. The first step is asking whether an individualized education program, usually called an IEP, or another accommodation plan fits. Extra time on tests, help with note-taking and seating changes are the kinds of adjustments that come up.
Six things to do while you wait for the appointment
Waits for adolescent mental health care are often long, and the 20% unmet-need figure is partly what that looks like in practice. The wait is not dead time.
- Ask the pediatrician what to do if things get worse before the appointment. Get a specific answer and write it down.
- Put 988 in their phone and in yours, under a name they’d dial.
- Check what your school already has. Many have a counselor or social worker who can start sooner than an outside clinic.
- Try FindTreatment.gov, the Substance Abuse and Mental Health Services Administration’s free and confidential search tool for mental health and substance use treatment.
- Hold the ordinary structure. Meals at roughly the same times, a workable sleep schedule, one thing on the calendar each week. Structure is not treatment, and it beats a house where everything has stopped.
- Keep asking, lightly. A short check-in every few days beats one long conversation a month.
Where sleep, movement and connection fit, and where they don’t
Both halves of this matter, and the second half gets dropped constantly.
The first half. These things genuinely help. CDC states plainly that healthy habits, including regular physical activity, adequate sleep for a child’s age and strong relationships, may help reduce symptoms alongside treatment. A 2026 network meta-analysis in BMC Psychiatry pooled 41 randomized trials covering 4,563 children and adolescents and found exercise associated with reductions in depressive symptoms, though the authors flagged substantial variation between studies and rated the overall certainty of evidence as low to moderate. A 2016 analysis in School Mental Health, led by Christina Pate, using a large national adolescent study, found that feeling connected to school acted as a protective factor for teenagers with emotional difficulties. And a four-year follow-up study published in 2020 in the Journal of Abnormal Child Psychology, led by Sunhye Bai, tracked 319 young people with a history of anxiety and found disrupted sleep and internalizing symptoms moved together in both directions over time.
The second half. None of that substitutes for treatment of a serious condition.
A teenager with major depression cannot exercise their way out of it, and telling them to try adds failure to what they’re already carrying. A young person who is self-harming needs clinical care, not a running schedule. CDC’s own framing is “alongside treatment,” and the preposition is the whole point.
The useful way to hold both: habits are the floor, not the ceiling. Protecting sleep, keeping some movement in the week and preserving one or two real friendships make everything else work better, including therapy. They are not the therapy.
What does treatment look like? NIMH describes it as psychotherapy, which it also calls talk therapy, or medication, or both together. As for whether it works: a 2017 meta-analysis in American Psychologist, led by John Weisz at Harvard, pooled five decades of research across 447 randomized trials and 30,431 young people. The researchers calculated that a young person receiving treatment had about a 63% chance of doing better than one in a control group. Effects were strongest for anxiety and more modest for depression, and the authors were open that the field still needs better therapies.
That’s an honest picture. Treatment helps most young people meaningfully. It is not a switch, and a first approach that doesn’t work is a reason to go back, not a reason to stop.
The one thing to hold onto
You do not have to know what’s wrong to do the right thing.
The threshold is weeks of duration, real distress, or interference with school, home or friendships. If any of those is true, you call the pediatrician and ask for an evaluation. That’s it. You are not diagnosing your child, and you are not overreacting by asking.
If the answer turns out to be an ordinary hard stretch, you’ll have lost one appointment and gained a baseline. If it turns out to be something more, CDC’s position is that early diagnosis and access to services make a real difference in how things go.
And if at any point the situation is unsafe, or your teenager talks about hurting themselves or someone else, call or text 988, or call 911. That part never waits for a referral.
