Hey there,
I am sorry that you are having to deal with this and that her parents are not understanding. Is there a way that you could teach them about self harm? Like print off thing on the interest that explains it to them. They might be acting this way out of fear. You could also, if either of you see therapist having the therapist explain or even a school counselor might help. Usually hearing it from someone of authority in that field can be beneficial. Try to show them that it's not an easy fix and that you both are helping each other to work on it.

Also remember that communication is key in relationships and through this period that is going to be tough because of her parents. You could write her letters and stick them in her locker at school. Remind her that you still love her and are there for her, that you guys will make it through this rut and that you aren't going anywhere.

Good luck!
