Some things you mention are clearly inappropriate. Parents get to discipline. But they don't get to be abusive. CPS is a terrible cesspool to get into - sometimes better the devil you know. I would reach out first to dad or a grandparent to ask one of them to pursue us today or guardianship of you. Your mom would not likely want these things she does to come out in court. As another option, if you are close with a friend's parent, they might reach out. Again, the difficulty is parents have priority, but what you have set out is not acceptable. Good luck.
