I never cut myself, but used to beat myself mercilessly. Once I nearly knocked myself out and saw stars and felt weird for several hours after. It gave me a headache for a while and worried I concussed myself I stopped this insane practice I was engaged in. Sometimes, I would beat myself bad enough to leave bruises and just pound my head with my fists in anger with myself. There were also a few times when I would bite myself but barely, if at all broke the skin but I bit down very hard. I even bashed myself on the head with a frying pan once when I was young. However, would this have been considered a form of "self injury" or not because never once did I cut myself, only punching and biting and stuff?
