This is a multi-faceted problem.
First of all, STOP! Do not cut yourself anymore!
The act of cutting is a response to deeper problem, generally the act of replacing emotional pain with physical pain to help cope. Your problems can be worked on without inflicting pain to youself. It is VERY IMPORTANT that you seek help for this. I understand your desire to to hurt yourself, but please, think of people around you who care about you, us included (we are a community after all).
Self-mutilation is not an answer, and your suicidal thoughts need to be addressed. Please think about this before hurting youself any further!
