I can’t get past this “in addition, I dislike living in small, remote towns.”. You should have not applied to Dartmouth if that was really true.
Be happy with what you have -own it and grow up. Don’t be the whiney kid with a bad attitude when you go to college…hopefully you are not telling other kids in your school about this issue. Many of them will not get into any of their top schools or may get in and not be able to attend because of money.
