Taera, I had very similar experiences in high school (it seems like many of us did). Now that I'm more than twenty years removed from them, I have a sense of perspective about them, but (surprise) they still hurt. I wouldn't go through those years again if you paid me. So, if it's any help, you're not alone in your experiences.
I'll bet, though, that you have a much better time of it at the university. You'll have a much better chance of meeting like-minded people, and he straight-jacket of conformity is a bit looser there because everyone is exploring their identities a bit more freely. Also, there are more diverse students and lifestyles, not everyone has come from the same place.
So, you have something to look forward to, but that doesn't help you now. You've already got some great advice about that, so I'll just add a couple of things here.
I have just recently started judo, and it's great. The physical activity is excellent for my depressed moods, it gives me a nice sense of mental and physical balance, and I feel more self confident dealing with people. I really should have done this when I was your age, when I really needed it (I was the hallway punching bag when I was 13). There are plenty of good martial arts available, from aikido to taikwondo, with a wide range of styles, levels of aggressiveness, and philosophical/spiritual levels. Just something to think about, anyway.
About your attractive friend - I can't stress enough what others have said here. These things take time, and friendship is an excellent way to begin a Lasting romantic relationship. My wife and I have been together for 18 years, been married for 11 of those, and she's still my best friend. Listen, really listen, to what she's telling you. Trust and good communication are the building blocks for a good relationship, and you'd be surprised at what she'll tell you about her hopes and fears if you are open to them. Eventually you will know her well enough as a friend to know if there's romance ahead. And even if there's not, you'll still be able to discuss it with her because you are good friends.
Lastly, and perhaps most importantly, hold on to your dreams. Even if it takes some time, you can make them happen. For those of us who have a tough time in high school, life does get better!
