they would either report you to your own therapist or a cop or something. when i was cutting myself they reported me to a youth service place called KYS. They said that since it was borderline personality disorder and not me actually trying to kill myself they would only keep up on me and not make me stay there in the rehab place. But I still was forced to go see my doctor every so often so he could check me out and make sure i wasnt cutting myself anymore. I also had to go to a therapist. There are ways they can report you. Trust me, Ive done it before and been reported on before.
