To test my threshold for pain. Maybe to prove to myself that I'm not weak, that I can stand the pain, that it's nothing really. When I cut myself the first time I was quite suprised by how little it hurt, though the blood loss made me weak for a couple days & I felt I could not even stand up. But that was a long time ago. Nowadays I deal with the fact that I can stand high amounts of pain all the time. I really don't need to hurt myself physically because I always end up in physical pain occuring on it's own. I even imagine what kinds of agony I could really end up in should I fall victim to confrontational violence that I am always avoiding, the place I live can hardly be called safe. I know the reasons differ for eveyone. If you have a reason, what is it? Do you even know?
