Everything Happens For A Reason. Right?

So, about a week and a half ago I tried out for this Open Mic that this Sorority I want to join is throwing. I sung Chris Borwn's Crawl and I thought I did good. But, I got rejected. They are having another event on Monday and I am not sure if I should go. Because I feel like I embarrassed myself. Maybe I really can't sing and and they think I am crazy for even trying. I hate rejection. I don't know what to do.
