Help me reverse my OCD?

You should go to psychiatrist because it sounds like you may need meds to treat your OCD. If you want to try to correct it, take baby steps. For instance, try to read a few words without articulating them, then try to read a few more. It may take you weeks or months, but if you do that, you'll slowly make some progress. You can try that for the other things as well. I would also go to a very good doctor or hospital to see if they can find a physical reason for your itching. For instance, some autistic people have a greater sensitivity to things, and there are treatments that can help them.
