Totally random here, but I just watched a crime show, can't remember which one, where a girl goes off the wall and the root cause was being raped while at college. Didn't want to tell her parents, acting out, etc. There's a lot of that going on in college. Maybe that's what set her off on this path?

Fo sho, too...they need to get her off that drug! It would be tough to saddle her with a mental type record for life, but OTOH, I'd rather do that than see one of mine die. If I were these parents, I'd be in court getting her declared incompetent and take it from there. But that's the nuclear option. How does she live, get money? Are they supporting her financially? Because I'd be cutting that shit off pronto and telling her to come home or she's cut off. Friends won't help her, but the risk is she will disappear on the streets.
