Okay. So Sunday night, I had a girl I'm interested over, and we were all having drinks and having a good time, and then I had one of my sudden mood swings, where I went from happily drinking, singing songs and enjoying the night to bawling my eyes out and wanting to kill myself. I got a friend to drop us all back home at my house, her and a couple of others went into the living room, I went to my bedroom where I layed on my bed and repetedly punched myself in the face, as hard as I could. I then went around headbutting doors, walls, metal bed poles, tv's, desks.. anything to damage my head. This is the first time I've ever used full force with my fists like that.. and it scares me that I'll do it again. Has anybody else ever done something like this? How do you refrain from that urge to just smash your fists, or other objects against your head and face?
