suicidal behaviour

Im 15 turning 16 in february. I have noticed that Im pretty much depressed all the time and I have mood swings very often. Its scareing me. I've threatend to kill myself more then once, I think about it alot. I'M to embarresed/scared to talk about it with other people, because when I did at the beginning maost of them thought it was a joke and started laughing. My parents and all the other people dont tke me seriouse either and its just getting worse.. I'm scared that I'll kill myself. I dont know what to do.

Suicidal thoughts are common symptoms with depression. Depressions are relatively easy to cure. SSRI drugs and cognitive psychotherapy are considered good methods. Contact a psychiatrist or a psychotherapist. You will hurt your family and friends terribly if you commit suicide.
