I'm just like you, I get nervous about these types of things. What I usually like to do, is be nice to the other girls, make the occasional joke, introduce yourself, find something you have in common with someone else! Ask where they are from? How long are they staying? Are they excited, because you are! I promise, you will make a friend or two very soon. Everyone is a little nervous at first when you go to camp, but once the ice is broken, everyone feels more comfortable with each other, its a lot easier to make friends. Just make yourself comfortable with some of the other people, and you will feel better! Promise!
