Cutting, anger and distrust issues; What do I do?!?!?!?!?

i am a very young girl but im not going to tell you that i know how you feel because in your particular sitution i am not you i am your friend. i have had a cutting problem ever since middle school it is not something that you can just walk away from because for me its an addiction its like being an alcohlic or a gruggy its not something that you can just take away....you need help. i have been to many therapists they dont help me because its hard for me to trust people and since i cant trust people i cant talk to anyone to help me. what you need to do is be her friend. she doesnt want someone to babysit her she wants someone she can talk to if she needs it or to have fun with when she wants it. dont call the police on her because girls like her and me cant controle our anger....literally. when we get pissed we go insane and cant stop until our body says stop and we wont realize what we have realy said or done until after we have done it. so stick with her dont give up on her she needs you
