Anger Issues

Ever since I was 8 I have had trouble controlling my anger issues. Anytime I would go to a brand new school with new people, I try to be nice. But someone always makes me upset and keeps pushing my buttons, to the point where my anger issues burst out. To the point, where once I was in 3rd grade and someone pissed me off, I got sent to the assistant principles office. And other times, I would just storm off and sit and cry somewhere. I know that I sound childish and dramatic. But the things people said to me in that grade really hurted my feelings.
