Excited or scared?

I am a loud-mouth. Everywhere I go, but especially in my nursing class at Northeastern University. It seems like I'm always the one answering questions, offering points of view, running study sessions, and asking the professor for favors on behalf of the whole class. At least once a week, I find myself in the front of the room addressing all 80 students. Needless to say, everyone knows me. So they all knew that I had been in Haiti, and when I got back, they all swarmed me, asking questions and talking about how cute my photos of the kids are. And within 2 weeks of classes starting, they were asking whether they could go to Haiti with me. I passed it off at first as typical college student enthusiasm that doesn't amount to anything, but they kept at me until I agreed. Today, I announced a potential trip for December and passed around a sign-up sheet, hoping for maybe 6 people.
25 people put their names on the list! 25!!! I was shocked, touched, and then a little guilty. I can't take 25 people to Haiti! Especially since I won't be there ahead of time to arrange things like beds, food, water, and transportation. So I discussed with my co-leader, Emily, and we have decided to chop it down to 10 students. The game-plan is to go down after our finals on the 13th and stay until the 23rd. We will spend the first half of the trip at a hospital or clinic, either Mother Theresa's hospital on Delmas 31 or the children's tuberculosis hospital on Delmas 40, and then we will just be at the orphanage, doing some health education with the young people in the neighborhood and playing with the kids. I think I'm crazy because it's going to involve so much work and so much supplies and so many $250 days with the tap-tap... but they are so gung-ho about it! And to be able to expose these girls to the Third World, to Christianity in a place where the people have nothing else, to see my kids again without having to put my medical career on hold - I think it'll be good. Actually, I think it'll be great, but I'm so scared right about now that the great and the petrified are balancing out to "good".
