...any self harm is no good
but how bad are you hurting yourself?...it's becoming apparent to you whats building up inside has nowhere to go....but back inside again?
you seem to have a solid concept of the future...looking six years ahead...
I hope the self harm...that it's just a phase for you!
it's good you have decided to talk about it somewhere
when I was your age I never hesitated to hurt myself...I'm ok now but it still shook me up so the only advice I can offer is to hesitate...
