Give yourself a break.

There are winners and there are losers. Sometimes, we just have to face the fact that we can't always get what we want. It's a humbling experience which allows us to get to know ourselves better. Know your strengths and weaknesses. You can't be good at everything but you can always try. Just don't be too hard on yourself. You're still young. You've still got a long way to go. Give yourself a break.
