ll be okay I think.. if they pushed me enough that my patience runs thin, I probably do it in front of them and then Threaten them to make their arms looks the same way, I'll probably get in trouble though but eh it's their fault, not mine. Making someone's mental illness fun is not cool at all, it's okay if you do it to yourself or the ones that get it cus of some coping mechanism but don't do it on others, especially when they never felt it before. They literally feel superior to me cause the never did "it", they feel strong and all, but really though when I argue them they repeat the same words again and again like middle schooler so... Yeah, they're just dumb and loud.
I'm sorry you experience something like that in the past, i might not relate 100% but I feel you. I really hope your life gets better someday, and the bullies.. I just wish they get the same experience as you or worse
