hmm i know i was 14 when i started cutting and have been in recovery for about 2 years now. i also know that when i was that age i would have loved for soemone to tell me it was ok and just have someone other than a family member to talk to. if you suspect there is a problem and i would say that that is a serious one at that, you might want to approach it slowly and build up trust and just talk to her. im not a professional but i know that that is what i needed at that age.
