I self harm. I've been doing it for well over 10 years. I haven't done it in awhile, but I still get the urges often. A lot of things can trigger it, my rage, my mood swings in general, if I think someone's about to abandon me(that doesn't take much), my feelings of emptiness, stress, anxiety/panic, etc. I did it because it helped me get some relief, or conversely because I wanted to punish myself. It's... complicated ...
