Social Media, Self-Harm, and Suicidality in Our Schools: Let's Talk

We live in a world where silence can be deadly.

Every day, young people navigate a digital landscape that shapes how they see themselves, how they relate to others, and how they cope with the pressures of growing up. Social media, while offering connection and creativity, has also become a source of comparison, anxiety, and deep emotional distress.

This is why talking openly about mental health, self-harm, and suicidality in schools and homes isn’t just important, it’s essential.

The Unseen Crisis

According to the World Health Organization, suicide is the fourth leading cause of death among 15–19-year-olds globally. In South Africa, data from the South African Depression and Anxiety Group (SADAG) reveals that 1 in 4 teens has considered suicide, and 75% of children who need mental health services don’t receive them. These are not just numbers. These are children sitting in our classrooms, walking our school corridors, scrolling quietly through Instagram and TikTok late at night. Many are silently hurting—masking their pain behind filters and emojis.

Why Social Media Matters

Social media is not inherently harmful, but for many teens, it has become a mirror that distorts rather than reflects. Research has shown that excessive use of platforms like Instagram and TikTok can increase feelings of low self-worth, anxiety, depression, and loneliness. Algorithms feed content based on engagement, which means teens vulnerable to self-harm or eating disorders are often shown more of the same, reinforcing unhealthy behaviours.

A 2023 study by the Journal of Adolescence found that teens who spent more than three hours a day on social media were twice as likely to experience poor mental health outcomes, including self-harming behaviours.

We cannot ignore the link between online life and emotional distress.

What Happens When We Start the Conversation

When we speak honestly and compassionately about these topics, we:

• Break the stigma around mental health.

• Equip parents and teachers with tools to identify warning signs.

• Offer children language to express their emotions.

• Create a culture of connection over silence.

• And perhaps most importantly, we help a young person feel seen and safe.

  
  

These talks aren't about scaring anyone. They’re about educating and empowering. They’re about building bridges between adults and teens—so that a child knows they can ask for help, and an adult knows how to respond.

My Mission

Through my school talks for parents, educators, and caregivers, I aim to bring light to what is often kept in the dark. With a background in psychology and counselling, and experience supporting families through crisis, I believe deeply that prevention begins with conversation.

We cannot afford to look away. The cost is too high. But when we lean in with curiosity, compassion, and courage, we begin to build a world where every child feels that their life matters.

Let’s keep talking.
