She thinks she's so out of my league and the rejection hurts

I got rejected by a girl who considers herself so much better looking than she actually is. As a result, when I'd normally have a shot with her (especially combined with my personality, which she loves), she thinks she's out of my league and is basically waiting for a 8, 9, or 10 to come along and whisk her away. I'm disappointed that she isn't taking me seriously and it hurts all the more that I got rejected by someone I so plainly had a shot with that it has ruined my confidence because if I can't get her, then how can I get anyone else?
