Going through rush alone :( what should I do?

[luckygirl]

i dont have anyone to go to the events with. my only two friends right now dont want to rush. i really want to though and have signed up and been accepted to go through recruitment. i am nervous of going to the events though because i will be arriving alone and dont know who to go to..ill feel awkward..the first event is this friday and its in a campus building where all the sororities are in this one huge room and the rushees will go socialize and talk to them and get to know what their sorority is all about. its gonna be so scary showing up alone..i do know some girls who are rushing and i might try and find them. but they are all really close best friends ..and also im not even sure if they like me bc last semester me and one of those girls had this guy problem going on and the other stepped in and basically told me to back off and so i dont even think im on good standing grounds with them now even though that was so long ago. should i still talk to them when i see them? what if they kinda give me the cold shoulder and arent friendly? what should i say to them? they are trying for the sorority that i rlly want too. (one of the only ones that will accept my lower gpa)
