I used to not be able to pee (shy bladder?) if a bathroom had even a single other person. But then I was in a situation where I had no choice (regularly) and I simply had to face my problem. It took _years_ and constant mental practice, but I simply got better at dealing with this and I am better off for it. I hope this works out for you, as I know most people will simply not be able to deal with their discomfort in the same way I did. And telling people to "face their problem" is not the same as saying "face your problem, and also I will make your life a little easier in the mean time."
