What should i do?

im in high school and i really wanna move out bc of my mom has threatened to hurt me and even kill me sometimes she has called me fat for no reason I barley eat anymore bc of my mom. I have wanted to call cps but i feel like they wouldn’t do anything. The things my mom has done is hit me when i was 12 the reason she hit me bc i didnt do something right i was in the shower and then told me I deserved it?!….btw my mom makes me do everything in the house I barely have any privacy anymore even today I thought I could stand up to her she was asking what i was watching on my tv and i said it was just a show and shes like u think your being funny how abt i take all of your stuff away so she forced me to tell her what show i was watching and she also said im the boss around here. I dont even have a actually phone i have a flip phone and i even asked her what would happen if one of my friends could give me their phone to borrow their phone and she said whatever is in my house i will smash it and even smash my iPad my friends mom gave me as a birthday gift when I was 13 I’m 16 now.. when I sneaked it From her took it to school she noticed it was gone and told every teacher I had it and I was so scared to go home.. and she thinks all my friends are bad ppl when their not ..my bsf I meet this year who is a really good person went to my school last year and now shes online and my mom thinks she’s a 30 yr old old man when she fr meet my bsf.. 😭🙏 and my bsf said I could move in with her when I turn 18!
