We can't hold a conversation?

So this girl I really like often tries to initiate conversation with me, and laughs way too much at my dumb jokes (those are the only signs she shows of liking me). Anyways, we're both pretty shy, and have difficulty holding conversation. I would like to ask her out but not only do I fear rejection, I also fear awkwardness because I am usually only good at talking with more outgoing people.
