Pretty much what Cray said. Those nerves will go out the window the moment you step into campus. Goodluck & all the best mate. Whose awesome? You're awesome!
Makes sure to try out many things to your interest. Narrow it down one baby step at a time. Try to keep distractions to a minimum....lest you may procrastinate if you're those type of students. Most of all, best of luck like everyone else says. Pardon my post.
I'd actually recommend you let yourself get distracted time and again. If you focus 100% on your studies it will burn you out and depress you. Be sure to take time to relax and forget your stress.
