K.W.
I would take her to a psychologist (not a psychiatrist - they deal with drugs to help disorders. They can diagnose, but they're also much more expensive). My husband has had OCD since that age and I just finished my degree in psychology, so with that being my background, my advice is to take her in. You won't get "stuck" in the system. But you may get an answer to your questions and if there is something, you'll get a diagnosis and ways to help her. To diagnose for OCD, you'll have to answer: Does it consume more than an hour a day? Is is severely interfering with normal life? With bleeding hands, I'd say that's serious enough to get the advice of a professional. It could just be a phase, but if it is, you'll feel better hearing it from a professional. Do it for her and for you. Good luck!
