That hit me hard... Everytime I take all I feel I can take from people, instead of lashing out at them, I take it out on myself. It's not good to do, though. Hurting yourself from pain others have caused you isn't healthy at all, but sometimes we say enough is enough and fall to the blade. I hope next time you can find something else to take that anger out on, like a punching bag or pillow or something that won't be physically harming you. Best of luck
