You can do this in several ways. First, get over yourself. I'm not saying don't be proud of your accomplishments, but remember that they are not who you are. When you arrive at college, nobody knows what you did in high school. The old labels don't apply any more.
College is a good time to make a fresh start.
Nobody will do this for you in college. But you'd better do it. Go to class in the morning even if you were up all night, dying from the flu. You can go. You have to go.
