Hey S&S, 2 of your top 3 choices is great! Don't forget about that! And if houses did cut because you are a sophomore, than who needs 'em anyway?
Try not to worry about who you aren't going back to and, concentrate on the great houses you are going back to! Like Chi Omega!!! Sorry, shameless plug!
Seriously, though, you have 5 great organizations to choose from! Just have fun!!!! Good Luck!
