Should I still join a sorority if I am socially awkward?

I will be rushing soon as a junior. I am a bit shy and introverted unless i get to know somebody one on one very well then I am my outgoing self. I have a hard time making conversations last even when I really want them too. I also feel like i don't fit in and that makes me think I won't get any bids. I am friendly and I do love people, I sometimes just get very anxious and nervous around them.

How can I work on this before I rush?
