chantillylace55,
It is going to be a wonderful experience for you! I can almost guarantee you that you will be nervous, but I can also almost guarantee you that the girls in the different sororities are going to be nervous themselves! It is a lot of fun, but there is nervousness on both sides. Don't let that keep you from finding the right "home" for you! Go with who you feel most comfortable with. It will all be just fine!
Good luck and have tons of fun! Don't forget to keep us posted!!!
