How do i have a mother and daughter relationship with my mother?

Me and my mom know nothing about each other. when i was just a month old she was sent to a mental hospital when i started elementary school she came back home she also started working so i barely saw her.she would leave before i was gone and would not be hope until 10 and i would be sleeping by that time when she was not working she went to bingo so i would barely see her.when i was in the 7th grade she stopped working then she started to drink she would hit me and have arguments with me and she still does i currently in the 11th grade. sometimes i wish she was not my mother. what should i do ?
