Sometimes you can just try again, wait for the time and the place, maybe after high school you two will meet in college or just as regular folk and she'll see you in a different light

Maybe you could be over-exaggerating your love, as wonderful as she may be there may be better. It's what I usually tell myself whenever I'm feeling down, with 6 billion crammed on to our small planet earth there has to be a lovelier lady once you move higher up in life.
Don't let it get to you man, just do your best to accept it and move on, maybe she'll decide she wants to be more than friends and will make sure to let you know.
