I have no idea why I started cutting, it was sort of an impulse decision. I continued though, because depression made me feel so empty inside (amybe this is why I started), like i had absolutely no emotion. I couldn't stand the pain of feeling nothing (does that make sense?), so the pain from cutting came as a relief. The answers for the rest of the questions are basically the same as what everyone else has been saying.
By the way, you don't sound ignorant
