How many people here live in a large city?

After close to four years in one I feel so suicidal that I'm just counting down the days until I resign from my job and go live with my mother again.

Every day I return to this naive, childish fantasy of living in an isolated rural environment yet I lack the money to do so, and even if I did I'd have to leave my country (UK) because it's so expensive and over-crowded.

Any tips or advice /out/?

Anybody here feel like detaching yourself from society as much as you are able?
