In my experience if you hate people the city is actually the best place to live.
Yes you're surrounded by a million people but they all ignore you.
In rural areas nobody has a personal bubble and you're supposed to do small talk and give a shit. Folks gossip. They know you. The horror...
You have to interact with people at some point, even if it's just when you get groceries. In rural areas, everyone knows everyone: you can't stay anonymous. In a big city, you probably don't even know your neighbors, and you choose your own friends.
