Don't be so upset about the result. After all, the game is not over yet.
Even if you didn't make it to the united states, it shouldn't and doesn't mean the end of the world. In my humble opinion, it only means that your qualities and strengths are not recognized by thoes professors or even yourself. So, even if you cannot study in US, you still have your FREEDOM to fulfill dreams and live the full of your personal life, which is far more important than anything else.
Sometimes, we don't have much choice to decide where we live or study, but we have the options to be the leading character in our personal drama. It is all up to ourselves to create chapters that have the content and meaning - created through everyday activities that bring us personal satisfaction. You never know what's gonna happen if you went to US someday, but by working hard with a clear personal goal everyday, you'll be happy anywhere, anytime, even you are alone sometimes.
I know it is hard, but I really hope this can cheer you up, and try to be a confident, and happy! You'll be ok!:)
