Have you considered seeing (or asking your parents if you are a minor) a counselor/therapist? They can help you with a lot of coping techniques, and maybe even some defense mechanisms. I'm sorry that you've been bullied - I really don't understand the mind set between people who dehumanize others. Ugh. It just ticks me off. I am sorry that you've resorted to self harm. Have you tried the rubber band method (popping a rubber band instead of self harming in more permanent ways)?
