high school senior, nervous for college.

Okay, so I was accepted to the art institute of san diego. San diego is 2 hours away from where I live. I don’t have a job or a car so I honestly don’t know how I’m going to do it. I have to get an apartment because it’s going to be me and my boyfriend moving over there. I don’t know how to start with that? Or what to do? I’m nervous. I’m really scared to mess up. Any advice?? Please.
