What to do?

It seems like only a few days ago I was having the best day of my life... however now it seems like those good days are all turning bad. It all started out today after school. One of my friends came up to me and told me that someone from her drama class asked her if I liked Celly... I had no clue how she figured out or anything but somehow she found out and I really want to find out how she found out. Then to make matters worse we are going on a trip in 4 days. Seems good right... well you are mistaken. Seeing as my hand is all screwed up I am not participating in the skiing or tubing that we are going to do. So, some of my friends think that it is more important to stay inside with me than to go outside and have fun. I want to tell them to enjoy themselves but they insist in staying with me. I mean it is not that I don't want them there, it is just that I kinda want some time to myself too sometimes and I don't want them to waste a perfectly good trip just because of me. I want them to know this but I guess I can't make that happen.
