Onc-
I agree with RoseQuartz, it sounds more like social anxiety disorder to me than OCD. If you're anxious about being in meetings or around people, your body will do some strange things to get you out of those situations, like make you think you have to go to the bathroom. Obviously if you go to the bathroom, you remove yourself from a situation that may be causing anxiety. I would recommend talking to your PCP and asking him if a light dose of an SSRI would benefit you.
