Sounds like you were standing up? I always sit. It gets easier to go in public. When I was on my 2 week intubation schedule I would go to Barnes and Noble. I had cabin fever so I just didn't stay at home and can go in any public restroom, hell I have even gone in my car once in a cup. Then I started going out a lot. Don't let it bother you too bad. Sh*t happens and move on.
