rush 15

I am really realy really wanting to rush this fall . i have been extremely hesitant for the past 2 years but i have never wanted to go through recruitment more . Only downfall is I will be a junior :( so I am afraid that is going to knock my chances ? I also am
Hesitant due to the fact that the sororities are primarily white and I don't want to shunned away because of that . Opinions ?
