Having been in a similar position, although not as forward as you, I would suggest you do your best to forget about her, because the worst case scenario is that she really isn't interested, and you become obssessed with her. This leads to complications, and potential bullying. Seen it, been there, didn't enjoy it.
Irony now is that the girl I am crazy about at the moment doesn't know it, but she knows about my inability to convey feelings and most of my other problems. In fact she is the only one at the moment I can confide in. Because of my condition, I guess you can say, I know that telling her how I feel will be the most difficult and uncomfortable thing to do, but we get along so well. It's a sticky situation and it is hard not to obssess, but I do it, I play with elastic bands, I come on here, I prep myself for my new job. I want to think about her all the time, but can't let that happen for my own sanity.
It's life, and it sucks at times, but you have to pull yourself up out of the rut you are in, take a breath, and move onward.
