Go for it! Just as everyone else as said...its worth it. I was in a similar situation. I grew up in a very small town and none of my friends were attending Texas Tech. I knew literally NO ONE at Tech. I went from a town with a population of 900, to Texas Tech w/a student body of 25,000. It was quite an adjustment, but being in a sorority and having the sisterhood helped me to adjust to the extreme change.
My mom was greek and she is the one that encouraged me to just give it a try. I went into it with an open mind. I knew absolutely NOTHING about any of the sororities except for KD (my mom was a KD). Recruitment was quite an experience and I wasn't for sure if it was for me. I kept an open mind throughout the week and I found my home. It was a perfect match.
I encourage you to continue on and go through recruitment. You don't want to look back 3 years from now when you are a jr. and when that you would've gone through. I had friends that were that way. You will find somewhere that you feel comfortable.
Keep your chin up! SMILE

!!! and Keep an open mind!!!!
