Being worried is natural! I'd be surprised if you weren't worried, at least somewhat!
When I was moving around a lot, I always went through a couple of stages with every move. The first month or so was always kinda rough, because I'd be bouncing between "this is all new and exciting! How fun!" to "I'm so homesick!" and "What have I gotten myself into?!?", but after that it'd just become "home", and I'd settle into a routine.
I don't like having no routine!
It's just going to be so weird. I'm sure it won't take me long to get used to things. But until I do, it'll be weird.
