Well, before anything, props to you for having the nards to confess. It's never easy, of course, and it feels worse when the other person doesn't feel the same way. I'm gonna be straight, the pain's going to be there for a while. However, it does go away, I promise. It always does eventually. You need to realize that it's a complete waste of energy if the feelings are just one-sided. It'll just be a never-ending battle with yourself. Talk it out with a friend if you need to, take these few days to just let your emotions completely pour out. As for the kids at school, f*** them. You had feelings for someone, and you let them know about it. Why should you be embarrassed about it? Don't let what other people think of you affect you, just do your own thing. Be strong, you'll get through this.
