Yes I agree to discuss this with your doctor. I suspect you're dealing with 'intrusive thoughts' linked to obsessive thinking which is a branch of OCD. Do you have any other compulsive actions that you have trouble controlling? The trick is, not getting upset or trying to repress the thoughts. Just because you're thinking about an embarrassing situation, doesn't mean you have the 'intention' to act on it. If the thought of eating garbage pops in my mind - it doesn't mean I want to eat it. Since these thoughts come when you're stressed - this is your minds ways of soothing yourself, although it doesn't feel soothing. Let your doctor know rather than worrying about it.
