Adolescence is Meant to be Messy. Here’s How to Tell When it’s Something More.
Parenting a teenager means holding two things at once: knowing that mood swings, door-slamming and sudden silences are a normal part of growing up and also knowing that sometimes those same behaviours are the first sign of something more serious. Adolescence is a period of rapid brain development, identity formation and emotional intensity, therefore it can be genuinely difficult to know where “typical teenage behaviour” ends and mental health concerns begin.
Why This Matters More Than Many Parents Realise
Adolescent mental health difficulties are far more common than most families realise. Research gathered from South African schools has found that as many as 47% of adolescents in some communities show symptoms of depression or anxiety, with even higher rates among those facing socioeconomic hardship. Across sub-Saharan Africa more broadly, studies estimate that roughly a quarter to a third of adolescents are living with clinically significant depression, anxiety or emotional and behavioural difficulties at any given time.
What concerns me most is not the prevalence itself, but the delay that occurs before help is sought. International research on treatment-seeking consistently shows that people wait years, even at times over a decade, between the first signs of a difficulty and the point at which professional support begins. This gap tends to be wider the younger a person is and in countries where mental health services are less accessible. This is precisely why early recognition is vital as the sooner a concern is identified, the more manageable and responsive to support it normally will be.
Signs That Are Often Missed
Not every difficult week signals a problem. What tends to distinguish between a normal adjustment and something requiring professional input is the duration, intensity and how many areas of life are affected. The following are signs I encourage parents not to dismiss too quickly:
- A change that has lasted more than two weeks: Everyone has rough days. What matters clinically is persistence. A noticeable shift in mood, energy or personality that continues for two weeks or longer rather than lifting on its own warrants attention.
- Sleep or appetite changes beyond typical teenage habits: Sleeping in on weekends is normal biology. Sleeping excessively every day, struggling to sleep at all, or a marked and sustained change in how much your teenager is eating are more reliable physical markers of depression and anxiety in young people.
- Withdrawal from friends, not just from parents: Teenagers pulling away from their parents is developmentally expected. However, withdrawal from friendships and activities they once enjoyed is not, and research shows that peer connection acts as a protective mechanism for adolescent mental health, so its loss is significant.
- A drop in school functioning that doesn’t match effort: A single disappointing test result is not a red flag. A sustained decline in grades, attendance or concentration, especially one that surprises teachers too, often reflects underlying difficulties with mood or anxiety rather than laziness.
- Physical complaints without a clear medical cause: Recurring headaches, stomach aches or fatigue that a doctor cannot explain are common presentations of anxiety in teenagers, particularly those who find it hard to describe what they are feeling.
- Increased irritability, conflict or risk-taking: Depression in teenagers frequently looks like anger or agitation rather than sadness, and a sudden willingness to take risks they previously wouldn’t have is worth paying attention to.
If Your Teen Mentions Wanting to Hurt Themselves or Not Wanting to Be Here
This sign stands apart from the others and requires immediate action, not a wait-and-see approach. Any comment about wanting to disappear, not wanting to wake up, or hurting themselves should be met with a calm, urgent conversation with a professional. Teenagers rarely say these things lightly, and they even more rarely repeat them if the first mention is met with real listening rather than panic or dismissal.
If your teenager is in immediate danger or has expressed intent to self-harm, please contact your nearest emergency room, SADAG (0800 21 22 23), or your GP without delay.
When to Seek Professional Support
There is no single symptom that confirms a teenager needs therapy and recognising two or three of the signs above does not mean something is catastrophically wrong or that you have failed as a parent. Adolescent brains are undergoing significant change, and many of these signs appear temporarily around exams, friendship difficulties or family stress before resolving naturally.
What tends to tip the balance toward professional support is a combination of factors: how long a change has lasted, how many areas of life it is affecting (home, school, friendships), and how much effort it is taking your teenager to hold things together day to day. Parents often have a quiet instinct that something isn’t right long before they act on it. That instinct is worth taking seriously.
It is also worth remembering that seeing a psychologist does not mean something is “wrong” with your child. Often, therapy offers a confidential space for a teenager to process things they are not yet ready to share with a parent, and it can ultimately strengthen rather than strain the relationship at home.
Taking the Next Step
If several of these signs feel familiar, you do not need to navigate the decision alone. I offer a free 15-minute intake call for parents who are unsure whether formal support is the right next step. There is no pressure and no obligation, simply an opportunity to talk it through with a registered professional. You are welcome to reach out to me via email or phone call.
Noticing is the first step. Support is the next.
