I love Judilyn's answer, but I also agree with pb4. I'm sorry to say that I used to be the person sitting next to the person making awful noises and thinking, "Geez, why doesn't she show some self-control? Doesn't she know someone else is in here?" Enter my UC. Ooohhh, now I get it. And now I'm the person in the other stall, hoping that the other bathroom users aren't thinking the same about me.
I do think that when someone doesn't understand your condition (or want to), you have no reason to be embarrassed. You didn't choose to have this, and you have no reason to be ashamed. Everyone always thinks people are thinking way worse things about them than they really are.
