i need help.

Ok, so far I have hurt myself 4times today. I need help, like put into a mental hospital. I need help to stop doing this to myself. I am not scared with my wounds but I'm scared that I won't stop when I need too. :( I have a cadet weekend; friday to sunday and there's a lot of fitness, like running and press up etc, I can't let myself go and hurt that bad that I can't do it. I'm part of a team and I can't let them down, I think this is the only thing stopping me do anything too silly. :/
