Senior year? You've got nothing to lose, you hardly know her and if she rejects you, you most likely won't ever see her again anyway. If you are shy and you don't have any good stories to talk to her about, you've got to lie. Go online and read some interesting and FUNNY stories, because if you can't make a girl laugh, she wont be interested in you for long. However, this will eventually stop working; this is more like an advice for a one night stand lol. But if you're not shy and an outgoing guy with a sense of humor, come up and talk to her. Girls love when you talk about their looks and their cloths, don't be too straight that you're interested though. Get a little cockyness in your attitude, they love it, trust me. I didn't say I hardly knew her, I said we've been kind of friends for a while. And my school has about 400 people, I most certainly will see her again :P I know that's not a good attitude to take with these things, being so self conscious, but I really can't help it, that's just me. To whoever said I had "one-itis" that's probably true. I hope no one judges me on this, but for some reason even thinking about her makes me feel awful. It makes no sense with my other feelings for her. It felt like this before summer last school year too, it kind of lessened in the summer, but as soon as I talked to her this year it came back. Maybe this is very normal, but I have no idea. I've never had any kind of relationship before, which as I mentioned before, is kind of sad for being a high school senior. I know there isn't really much advice I can be given for this, but at the moment I'm more just venting, I've never really talked to anyone about things like this before.
