The document discusses mental disorders and their relationship to suicide. It notes that mental disorders like depression and bipolar disorder can cause the brain to function abnormally and result in suicidal thoughts. Many teens with mental disorders feel like outcasts in society and that frustration with themselves and society can lead them to consider suicide. Bullying is also discussed as a factor, as bullied teens often feel worthless with very low self-esteem, leading them to depression and potentially suicide. Early detection of mental disorders and treatment is important but not always effective in preventing suicide.
