I am thinking about starting a new life, Im 14, What should I do?

Hi, my name is max and I recently went to my cousins house in the countryside of the eastern U.S. I live in NYC currently, I am starting to think I don't belong here. I have recently transferred schools and i enjoy the people there, but i feel that I have not been myself around these people. And also I feel that I am smarter than most of them. I know I sound stuck-up and selfish in this but I don't know what to do. When I went to my cousins house I felt that I could be myself around his friends and I felt like I was having more fun with them than I have with my friends in NYC. I have contemplated this thought for a while and I see that the only way I could start a new life is if I get expelled from school and my parents will send me out of the city because of the unhealthy effect it has on me. I see no other options besides going through with my plan to go to the countryside and become happy or staying in NYC and not become as happy as I could.
