It's a time of great change right now and fear is a natural response. The world is going to be a very different place in 4 years time. Try not to let the fear of an unknown future affect your experience in college. College is a great time to learn who you are, to learn what you like and what you dislike, make friends, understand people, pick up new skills and hobbies and drop old ones. I don't know you and where you're headed, but I know you're going to have a great time. Enjoy it and let the future come to you.
