I thought I was the only person who did this... Every time I get mad, especially when I'm mad AT someone, I have to desperately fight the urge to hurt myself. This only ever makes it harder to handle my emotions, and doesn't always work. I have hit my thighs l, my knees, and the sides of my skull on several occasions. I thought I was crazy because I couldn't get mad without wanting to hurt myself. I couldn't make mistakes without needing to punish myself for it... I never realized it might be because processing physical pain is easier for me than processing anger...
