I cut to release my anger, sadness...primarily all directed at myself. And because it feels good and calm(ed) me down. I happen to love the taste of blood. But that doesn't work anymore, calming down, so I guess I just cut when I feel like it...
I bang my head against the wall because I'm trying to knock myself out...and for many other reasons, like simply being angry at myself. But to knock myself out mostly. I NEED to be knocked out, like a permanent coma or something...
I squeeze my head because I hate the skin I'm in.
