This sounds way to familar, as someone with adhd who is pretty laidback and has anger issues this hits close to home... Im the type of person who's in control of their emotions to some extent, For example: when I was younger I'd always wanted people to like me, soo much that I'd do anything to make them happy. Even if it meant being a tool... so one day I was helping my "friend" with her math homework. And by helping I mean letting her copy my paper. After she finish copying she crumbles up my paper and throws it in my face... normally this would set anyone off but I ignored it, and it continues, a week passed by I just held in my anger that entire time. I was having a bad day by the time i went to class that day I was in no mood for shinanegins so that time I didn't let her borrow my paper... the current events that were about to unfold was nothing but intense rage, So since I had not gave her my paper she started to make fun of me. Now I was already on edge so one word from her mouth and I was about to go psycho on her ass. She said I was stupid... I didn't let her finish that sentence I got the fuck up out my chair charged towards her desk an proceeded to yell at the top off my lungs every cuss word ever rude comment i could think of I told her off at this point I had grabbed her and threw her to the ground while still yelling at her after I was done the speechless bitch was white as a ghost, in fact everyone was.... I'd stormed out of class that day and since that day no one dare said a word to me. So there my long story. But I've learned to contain my self, those out bursts are still a problem i need to work on though.
