I can't speak for your mom but the reason I would hit them is because they would make me really mad, I had a really bad anger problem my whole life, I was out of control. Just recently I've started to control it better. I haven't physically fought anybody in 4 years and whenever I would fight people I didn't genuinely care about I never apologized but still feel bad about the damage I did to them to this day. So why I would apologize, because I had genuine feelings of love for the people I was hurting, I felt bad about what I had done and I didn't want them to hate me forever. More reasons why: I had been abused in a very similar manner except I never got the apology so it was a lot harder for me to find forgiveness, plus I didn't want them to try to kill me in my sleep, or go telling the police about what happened.

Oh they are prescribed meds, I assume the sedatives are to? Or are those hers? When you see your psychiatrist you should ask him to give you and your mom a recommendation to see a family therapist. Then in therapists office you two can work things out. If that doesn't work you could always report the abuse to your psychiatrist. Its against the law to abuse disadvantaged people, children disabled etc.

I don't doubt that you have some issues but schizophrenia is taking it a little far, judging by your other posts it sounds like you could benefit more from seeing a good therapist than you are from the psychotropic drugging. I was in a very similar situation to yours when I was a child/tween/teen. I lived in an abusive home and was undergoing psychiatric treatment and psychotherapy for "mental disorders" that were really just side effects of the abuse. If I could've stopped the abuse and neglect I probably never would have ended up with PTSD. If I would've never went to psychotherapy I would've never stopped self-injuring either.
