I have a weird problem that only just started happening. When I shower I slap myself across the face. It started because I like the sound of the water when my hand hits my face. I used to do it once or twice then stop but that was months ago.

Now is a different story. Even before I'm in the shower I'm slapping my face from excitement, then once I'm in I don't stop. Sometimes I even forget to wash, I just spend the whole time in there slapping myself stupid. It's to the point that not only is my face red raw by the end, I've actually left marks on my face and broken blood vessels.

I know it's very fucked up by I need some kind of strategy to stop this, at the moment it's practically a reflex action that I can't control.
