Whew - your story brings back memories ! I knew where the bathroom was in every store, and every road from home to all towns around me ! Its part of the irrational thinking that we develop with panic attacks - catastrophizing. I wrote rational self statements on a 3x5 card such as "I dont always have to find a bathroom when I am out", "If I need to find a bathroom, I certainly have enough time to do so before there is an accident", rather than thinking "I ALWAYS have to go to the bathroom when I am out", etc. I read that card literally 1,000's of times, until my "stinkin thinkin" changed to more rational thoughts. (Assuming you are female - Depends or something along that line are wonderful to wear if you are really obsessing, OR if you are going to be somewhere there is no easily accessible bathroom). You are not alone with this problem, and it is one you can overcome.
