If you are moving to the beach area, think about learning to surf! Surf, sail, fish - what a way to spend your teen years!
I'll tell you straight up that moving is disruptive. I'm about to move to NC, too, and I'm pretty nervous myself! I think that knowing what to expect helps.
I've moved lots of times and there are several things I like to do to prepare.
First, I don't like feeling lost. So, I go get maps of the area I am moving to. If your dad belongs to AAA he can get maps of the area for free. Otherwise, go buy one at a bookstore. I have found that if I look at the map before I arrive, I can know the names of the major streets that go north and south, and the major east-west routes, too. When I get settled, I mark where I'm living on the map. Then when I'm out wandering around in my new town, if I get lost I never have to go too far to find a road name I recognize and then I can orient myself.
Next, I also like to read the newspaper where I'm going to see what's going on in the town. The Jacksonville Daily News is the paper for the town where I am going.
http://www.jdnews.com/ Reading the paper tells me lots about the community because I can see how it's like where I live now and how it is different. I like to look at the classifieds, too - is the car I dream about cheaper or more expensive to buy there? What kind of sporting equipment takes up the most classified ad space - that tells me a lot about what people are doing for fun.
Reading forums like this one are also helpful. If you are using a social networking site like Facebook ask your friends who they know in NC, and they might introduce you to soe new friends.
It is wise to anticipate some discomfort with your move because then you will be prepared for it. Being "homesick" is normal. But it will not last forever and it won't kill you. You'll make some new friends and before you know it, you will be enjoying the new place.
Best of luck to you!
