I'd never laugh about doing something to calm your nerves and I doubt anyone else here would unless they had tried it too and then it would be laughing with you, not at you Mari. I am sorry you have to go through all that stress with getting up early and all the problems of figuring out what to wear and all. It's definitely not my favorite thing to do either, I am better now with my BP II and speaking, much calmer, but I still HATE talking to people because I feel like I am making a fool of myself.
Anyway good luck today, I hope you get some good rest after this luncheon. You deserve some good sleep.
