I'd honestly switch schools or something. There's a girl at my school who cuts herself (see: wristbands) and actually failed committing Self Delete. At one point I saw her slam a door open and then proceed to vigorously scratch her wristband with an angryfaec.
Everyone always talks about her and she has to sit with the autistic kids whenever there's a speech or whatever in the cafeteria.
And come to think of it I haven't seen her since before Christmas, and I've got PE with her.
