Help with fitting in? finding friends?

Here's the problem: I moved into a completely different city, i'm a jr in high school, and I'm completely friendless. Here's how it all went down: See, my first day was yesterday, I didn't actually "start" school until 4th period. I don't mean to sound cocky, but at my old school I have always been part of the "in" crowd. I figured, if I played it right I could join this schools. We moved into a runt of a town, I imagined people would talk with a country accent and i'd be surrounded by idiotic hillbilly's. Well, I was wrong. See, I managed to make my way into 4th period pretty quickly. I figured I could sit there and watch the kids come in, scoping them out, getting used to all the cliques. Well, this girl comes in. Out of nowhere the punk dude behind me gets up and starts yelling her name, and the other 5 kids in the room all stand up and clap including the teacher (she had won the talent show the night before). When she saw me she tried to make her way towards me and say hi but I just rolled my eyes, she seemed pissed off. In the middle of class then, she blurts out: "where are max and ruby's parents??!?!?" 3 cute boys I had my eye on all laugh and I just smiled and rolled my eyes again (that's a habit me and my old friends did). After that the class had to split into groups. The 3 cute boys chose the girl and she invited me over. I would've sworn one of them was flirting with me. Except when the girl walked out, he grinned and said, "Woo, man, she's hot." The other two agreed and they complained about how she's taken. The boys wouldn't talk to me unless the girl did, I felt so humiliated. Except then one asked me why I rolled my eyes to much, then he said it was snobby. The girl asked me if she could borrow my pen, and not to be rude, but i'm very picky with lending my things so I said no. She just muttered back, "oh jeez," all sarcastically. Later at lunch I met up with a few girls and we started talking, I told them I was new and they told me I could sit with them. Well, at their table were the 3 guys and one of them said really loudly, "ah! it's the pen girl!" Obviously he had told everyone about it, but made me sound all bitchy in it. Some other guy randomly says, "our seats are all full." I ended up eating lunch at the office. Since that didnt go so well, I figure I could make it up in choir, as fate would have it, she's in there. And, she happens to be the favorite student. That didnt go so well either. After school I went to check out the soccer team and this really, and I mean, really, hot guy bumps into me and we start chatting. Well he basically welcomes me into the school and says that if I want to join the team I have to talk to the coach, he walked me over there. I was able to sit in during practice and I saw the cute boy, then I saw...her. They kept flirting with eachother and it turns out he's her boyfriend! Worst. Day. Ever. See, I figured she must be a good person if she's friends with literally every clique in school, and have a very nice boyfriend. But i've made the wrong impression on her, any way I can get her to change hermind about me?
