15 and I want to move out ?!

okay so this might sound stupid but here come nothing .. I'm currently 15 and I want to move out from my mom house she's always angry and screams at me for no reason .. I help her with everything I can but for her it's not enough I do good at school .. she doesn't even cares about that either .. I have a bf , btw she already met him but she doesn't like him coming over to my house (where she could actually see us) i guess she rather us go out behind her back .. she beats me she doesn't hits me whatever she got she hits me with it I'm tired of this crap I can't do it anymore .. My only option is to move out .. either with my bf or best friend ..!
