Everybody worries. Yours sounds like classic new-school worry. After you make some friends, it will go away. I changed schools a lot growing up, and I found that joining something is a great ice breaker. You could sign up for sports, band, clubs, or any other group hat appeals to you. At different times and in differrent schools, I belonged to the drama club, rifle team, astronomy club, school newspaper, and such as that. Not being musical or athletic limited my choices, but I still found some interesting groups to join. And I always wound up with some instant friends.

Second thought: Buy yourself a Kentucky Wildcats tee shirt and become a fan.
