Entry #21 — The Star: Why Young Lives Fade Too Soon

A big study from the World Health Organization in 2025 shows that over 720,000 people die by suicide each year worldwide. For young folks aged 15 to 29, it's the third top cause of death. That's more than car crashes or many illnesses in that age group.

Picture Alex, a 22-year-old college student full of dreams. He loves drawing comics and hanging out with friends, but lately, things feel heavy. School pressure builds up, a breakup hits hard, and scrolling online makes him feel like everyone's doing better. One night, alone in his room, the dark thoughts creep in stronger than ever. He wonders if anyone would notice if he was gone. Alex isn't real, but his story echoes many young people who feel stuck in silence.

Breaking Down the Science Simply

Suicide means ending one's own life, and it's a big issue for youth around the world. Guys often have higher rates than girls—about twice as many, from global numbers. But girls might try more often, while guys succeed more due to methods used. Age matters too: in teens (15-19), rates can spike from school stress or bullying. For young adults (20-29), it's job worries, money troubles, or broken relationships.

Where you live changes things. In some countries like the U.S., rates are higher in rural spots with less help around. Cultures play a part— in places with strong stigma against talking about feelings, people hide pain more. For example, in some Asian countries, high school pressure leads to more cases, while in the West, social media and loneliness add fuel.

Why so high in youth? Brains are still growing until about 25, making it hard to handle big emotions or see long-term hope. Common triggers: feeling hopeless from mental health issues like sadness or worry (affects 1 in 7 teens), bad experiences like abuse or loss, harmful drinking or drugs, and tough life stuff like poverty or discrimination. LGBTQ+ youth face extra risk from rejection. Social media can make comparisons hurt, and easy access to dangerous things worsens it. But it's not one reason—it's a mix, and stigma stops many from asking for help.

Good news: talking openly, better mental health support, and things like school programs can lower rates. Countries with strong help lines and anti-bullying rules see drops.
