sorority dues

Hi im an incoming freshman and registered for fall 2015 recruitment and i have a big issue. I didnt realize that dues for sororities were between $2500-$4000 per semester and my family isnt in a financial situation to just write checks out like that out of pocket. How does everyone afford these dues? Do you take out loans or do your parents pay for it? I dont want to go through recruitment and fall in love with a sorority only to find out i cant afford it. I also dont want my social life these next 4 years to be dictated because I cant afford a sorority. I just dont know what to do and really need help from someone thats in my same situation? I cant believe that the thousands of girls in sororities at FSU just write out checks each year for about $7k and have no problem doing. Thank you for the help!
