How many teens commit suicide each year because of bullying?

Just one is too many. We don't have an exact number. In the US suicide is the third leading cause of death amongst teenagers and adolescents. A British study reported 44% of suicides occurring in kids 10 to 14 was caused by bullying. Those bullied often remain silent until the emotional trauma is eventually no longer tolerable. Cyberbullying is a particularly malignant form of bullying.
