I beat the shit out of my brother about once a month for years, and it's only partially what it sounds like. So I had a really rough childhood, mom died at 4, and my dad was horrendously abusive from since I can remember, till he threw me out at 16, and I got, as my therapist put it "severe mental trauma", I've been diagnosed with things like ptsd, paranoia, can't remember the diagnoses, but severe anxiety and depression disorders, along with at the time, pretty bad anger issues. My brother(2 years older) always thought it was funny to exploit those anger issues by saying some pretty fucked things to me, for example "kill yourself you worthless peice of shit", or "I'll get you sent back to the psyche ward you fucking freak".(for context, first psyche ward visit I was 12, total time about 2.5 years at 18, first suicide attempt was at 11, total attempts, over 20, honestly lost count) Which would always result in me beating the hell out of him, for example, I have body slammed him through a glass table, pushed him to the ground and kicked him until forced to stop, ect. And because he had cerebral palsy, and because my father only abused me, I was always sent to a psyche ward and/or, got a couple broken bones from my loving father, this went on from when I was 12, to when I was kicked out at 16. To this day I have no idea why my brother continuously antagonize and berated me, he knew what came next, and towards the end he was terrified of me, but continued doing it, I have a feeling I am at minimum partially at fault, but I wanted an outside opinion, last thoughts, my brother never got any serious injuries, like broken bones or torn muscles or anything like that to my knowlege as a result of me hurting him
