From what I've seen, you can be the ugliest person on the planet. But as long as you convey some confidence and put yourself out there you can achieve anything!
I personally have been single for what I think is a long time. Yes, it bothers me, though I don't let it affect me or put me down. I'm still young, in time I'm sure I will find 'the one'.
Who knows, maybe this crush will work out.
