If your from the Uk visit this site. http://www.samaritans.org/

If not I'm sure there is plenty of websites and hotlines out there to help you cope.

I'm not going to go in depth but I'm just going to tell you one thing, you have to much to live for to throw it away. A lot of people, especially teenagers have suicidal thoughts, I'm speaking from experience but seriously you have so much to live for. If you commit suicide your throwing away a life of possibility. You can do anything you want if you put your mind to it, now tell me why you would want to throw that away?

Your probably in a dark place right now but seriously, there is a light at the end of the tunnel.
