Thanks for the input guys. I don't think it's just my age because my mom says I've been that way since she can remember, the slapping her was when I was 5.
I'm going to talk to my mom and step-dad about possibly getting a medical diagnosis. I already have been tested for ADD, OCD, and some other things which I have. I've never been able to know the why other people react to certain things, and vise virsa.
