I always need to pee when I'm nervous about something, particularly it seems if I have to get up and speak in front of some people, or if I'm doing something like meeting a blind date or whatever.
It's really annoying because it feels really desperate, like I need to go right now, but then there's very little going on. And often it involves dashing away from whatever event I'm about to participate in.
I know I could not be a movie star, that's for sure. I'd have to include a clause in all my contracts: must have toilet close by.
I find though, that as soon as I get up there, or meet the person, or whatever, the need vanishes. I don't even notice it going, because I'm too busy, but afterwards I can't remember regretting if I didn't make it to the toilet.
So, maybe grin and bear it is the best option most of the time?
