growing up, my mom's voice was always that i was doing something wrong, even though I was an A+ student & very well behaved. no matter?

what i did she criticized it--if i styled my hair, i was "being shallow". if i didn't style it, i was "being a slob". nothing i ever did was right. she didn't make food for me. she hit me in the face. she didn't pick me up on time from school, leaving me alone at the playground for hours in freezing temperatures. she would disappear for months with no word. she would pull us out of school for months on end. she would move us away from our dad and made 4 of us sleep in a car. by the time i was 13 i quit talking to her completely because i was tired of being criticized. when i was 19 i moved out without telling her where i was going. now i'm 28 and i'm not particularly angry with her, but i see how wrong the way she treated me is (i didn't see it as a kid) and now i am wondering what issues i may need to work through due to all this mistreatment
