Divorce

So i am 13 yrs old and my mother used to emotionally torture my in the past (6 years - a bit of 13 yrs)by hitting, emotional neglect, giving little to no privacy , passing bad comments and jokes on my body and even though she said she will improve but i can't forgive her and because of her i even started self harm and overthinking and i got social anxiety and i got very insecure and socially with drawled and i feel that staying away from her would be better also i have a younger brother he is 8 years old and my mom brain washed him in thinking i am wrong and she is right . Me and my mom often have arguements so my brother always take my mom's side thinking she could never do wrong but i want my parents to have a divorce because she also used to hit my father sometimes when she got angry and today only I saw her checking my fathers phone without his permission while he was sleeping and she also used to also check my phone just a few months back without my permission but i never thought she would check my father's messages . so i want my parents to get a divorce and for me and my brothers well being i want my mother to leave us and i want me and my brother to live with my father for our safety . So what should i do?
