financial questions

I am planning on joining a sorority, but most of my funding for school is through financial aid. I'm on scholarships/grants and am taking out loans. How does that work with living expenses? I know a lot of the girls there are very well off, and I'm not. Will that affect me greatly or make them judge me?

If I'm calculating my Financial Aid correctly, I should be able to pay for living expenses/dues with the money I have left over. Is anyone in the same boat and use loans to pay for living expenses? Can someone break down the cost of living at their sorority, when their expenses were due (monthly, quarterly, etc.)
