I am scared of my dad because he always yell at me. When I don't know something he calls me stupid (I mean the meaner version of stupid, the word that starts with r). I am borderline autistic, and I don't know when I am doing anything wrong half the time. He always talk about something on the lines of "you guys have it better than most people". Sometimes he would slap me in the face, not because of discipline, but because of something else, like anger or something. The slap is not small, he is using almost all his force, he slaps so hard to the point where I fell dazed, almost lightheaded and dizzy. I have been planning to run away or something, I just can't handle this. Please tell me what I should do!
