In my experience, people adapt pretty quickly, especially at your age. I personally think it is fun to experience conditions–whether the size of a city, rural/urban, or weather–that I am not used to. My daughter, who grew up in Florida, is planning to apply to the Maine LACs if she isn’t accepted at her ED choice, and is excited about potentially going to school up there. I think she is also excited about having the opportunity to buy a whole new wardrobe!
Colby is a great school–good luck!
