It makes sense to me that you're angry at people who seem like an abuser. Actually not mad at brother, or not allowed to be mad? If you blocking/denying that anger, even more reason you get mad at people who seem like him.
My brother started when I was in grade 3 by calling me stupid, dumb, and told me to go away whenever I saw him at school. He humiliated me in front of my friends and his friends. He contributed GREATLY to my OCD. He made fun of my Tourette. He told me to only focus on the negative aspects of my accomplishments, because if I focus too much on the positive aspects of the things I\'ve done, I\'ll get cocky and prideful. Sometimes we fought, and it got really physical. The last time we fought, I tried choking him. I remember one fight we had. I told my brother when I was in grade 7 that I wanted to be a pilot. He said I can\'t because I have Tourettes which is a complete lie. We ended up arguing, and in the end I threw a pillow at him. It missed and hit his laptop. He went berserk. Nowadays, I get angry at people who remind me of my brother, NOT at my brother himself. Why is that?
