Should I just give up on everything?

Now I know that is quitter talk and I hate to say it but it is true. This is my story: I don't have any friends and I'm a junior in high school, I know its pretty cliche on this site but this is serious. I'm not socially awkward at all and I think I'm pretty cool but honestly that doesn't matter when your unattractive. I live in an area where if you are ugly then it is impossible to be happy. I go to school everyday, I make jokes, I'm not annoying, and I'm really cool to talk to but everyone ignores or avoids me like wtf did I do. I have a sort of weird shaped head where the bottom of my forehead slants forward. My hair is very thick so it is short and my teeth are kind of messed up and I cannot afford to fix it. But those things are small, the biggest problem is my skin color, I'm hispanic and so my skin is naturally tan, you would think that's a good thing but apparently it isn't. In my school either your white or black, everyone is messed up to those in between for some reason which doesn't help me at all. People take one good look at me and think "I don't even want to go there". I was even on the football team and still people hated me. I have no idea how to act anymore, if I go any further it would look like I'm trying hard. What should I do? I get embarrassed by something everyday and school really sucks. How will someone like me make friends?
