It sounds to me like you are pretty good at doing this already. You made the perfect intro for us, I'm sure others (without cf) would feel the same. I think sometimes it is good for "normal' people to understand that we don't want to "show" our sickness, but how devistatig it can be. Be yourself I'm sure you will do fine. My mother always told me God will help you do anything, especially if you are doing it to help others. Raising money for cf research etc is definately helping others, so say a quick little prayer...He will help.
