What to do about low self-esteem?

[Lotto]

To start, I have never had a girlfriend in my whole life and I'm 16. I have been told by many people that I'm ugly as well as skin and bones. People have told me that if they saw me in a relationship that they would puke all over themselves. To top all of that off I'm gay and it seems I will never find a guy that would like someone like me. I like guys that are just the opposite of me (muscular) and my friends have told me that no muscular guy would be attracted to someone like me. I am a nice person and I do make good grades, but that doesn't seem to do the trick. I live in a small town where being gay is disgusting and intolerable and I feel like I'm all alone and will never find love. I've had two crushes in the past that have done just that... crushed me. Both boys had a facebook, one didn't even accept my friend request while the other one did, but wouldn't even talk to me! I am just so tired of being single and feeling like an ugly duckling. Is there any place i can go at 16 to meet that special someone?
Also... what do I need to do to feel better about myself? This is really depressing me.
