Do I have OCD? please help?

Your diagnosis of ADD and SAD is important to know, but the truth is, no one here can tell you for sure if you have OCD. I am close to some people who are diagnosed with it, and it does not always present itself in the way we typically hear about it, so it is not impossible. But sometimes a person with one neurochemical problem (ADD) is eventually found to have others as well. These are very complicated issues that can often be treated, if they are properly diagnosed. I am assuming your diagnosis of ADD was by an expert and not just a pediatrician unfamiliar with it. A real diagnosis involves quite a bit of testing, of different kinds. You should talk to your parents and get in to see a psychiatrist or a good psychologist to determine what is going on, and whether you need some counseling or other form of treatment. You may be fine. Better to see a professional now and learn that, than to worry about it instead of focusing on your schoolwork and being a teenager. Good luck.
