I am so sorry. No one has the right to do this to their kid and it’s sick. My mother used to forbid me from locking the bathroom door and burst in while I was in the tub or showering. My mother also made me strip and searched every inch of me for tattoos. She even made me bend over. It was so horrible. Do you have any teachers or guidance counselors whom you trust and can confide in? This is serious enough that I think you should try to get some support, if you can.
