For the past few years I've noticed that when I get super upset/angry In the moment I end up inflicting harm onto myself, like whether it's banging my head on the wall or even punching myself. I've given myself bruises, and I've gotten myself incredibly lightheaded and almost blacked out from it before, I don't know why I do it, but I've been told it could be an issue caused by my ADHD? I'm getting tired of these sudden attacks and I don't want any more bruises or issues because of it. Has anyone else had the same problem? And how do you manage it?
