you better go for it!!
seriously, i have been in your shoes. don't knock it til you try it. you have already signed up for it, so what if it meant to be that you go through rush. it is a great experience. and rush at UF? that means that you have a wonderful opportunity ahead of you. just go in with a happy heart and put your best self forward. you have no idea of the sororities that can benefit well from you. it is not as bad as you think. just give EVERY sorority a chance. if you want to be in a sorority, then just follow your heart.
