There isn't anything wrong with being clean or healthy. You just need to find a happy medium. You need to convince yourself that one time of washing your hands is enough. Washing them again will not make them any cleaner. I liked what was said earlier... keep in mind that over-washing is just opening you up to infection. Try thinking about that when you go to wash your hands. It might help you convince yourself to stick with one time. Also, being around people builds up your immunity to fight big illnesses. I would stand away from sick people too, but try to just calm your actions down a little bit. Think of it like volume, take down your obsessions one setting at a time. Baby steps.

Good luck!
