20, 6’4 woman, keep getting rejected because of my height

I'm a 20 year old 6'4 woman who's never been able to find a date. Guys frequently tell me straight up that I'm too tall for them. I'm not fat (160 lbs), I take care of myself, I shave, do my hair, et cetera. So I'm not horribly unappealing. And I have lots of friends, so I'm not mean or awkward. It's especially hard because I like short guys best. 5'10 or under guys are the cutest, and I'd love my guy to be a lot shorter than me, but guys just don't want that it seems. Am I screwed? What do I do?
