I was telling my husband about that episode w/Cristy today. He doesn't watch the show. Anyway, IMO, Other than the drugs, I really think there was something wrong w/her to begin with? Just watching her as a child she seemed exceptionally hyper. I don't know, I mean, what about people that are ill to begin with and end up doing drugs? For example bi-polar? I know the drugs had everything to do with her actions but she was the worst case I think I've seen on that show. Throughout the intervention she was laughing.
