Feelings of RAGE?!!!?

sometimes i get feelings of rage and very intense anger out of no where and i think of unpleasant things lik people cutting themselves.. like i literally imagine a person putting a razor to their wrist and cutting deep through their veins and blood just bursts out.. then i get th feeling that i want to hurt myself.. not cut but just bang my body parts agaist things but i know i cant really do intense harm to myself because im afraid to endure that much pain. but i listen to music that influences me to do things like this.. i feel high like im getting high from the music.. then i get dpressed and angry... does this have to do with some chemical in my brain that is released to make me feel like this????
