You have a lot of support behind you. Your mom is just doing what she thinks she needs to do to keep you safe. I'ts good that you can talk to her. Most can't talk to a family member. And let the school counselor help you as much as she can.

Sounds like you had a very good art project going. There must have been a lot of feeling in it. Keep up the artwork. It will at times keep you safe, I know from experience. Good luck to you. Remember you are worth it and you can let go of self harm.
