At the root of this terrible reality is depression. Depression affects people of all ages, but the adolescent years carry special risks. This is a time of transition, and it's often very stressful.
Most young people handle the ups, downs and uncertainties fairly well.
They may start 'self-medicating' their pain with alcohol or other drugs, or they may turn to acts of violence. They are reluctant to talk about their emotions or problems, thinking this will make them a burden, or fearing others will ridicule them. Seek professional help immediately. Most young people who attempt to take their own lives do talk about it first. Not all depressed teens commit suicide.
