This was how Brave New World ended. The protagonist who never had a happy life at his old place but adopted their beliefs moved with Bernard back to London. London is like all the world except where said protagonist came from and maybe the islands (unless those fall under Released to Elsewhere).

The narrator theorises this - no, she states it as a matter of fact - in one of the very last entries in her journal before she tries to burn down her school; as her mental health was already deteriorating quite early on, we are left unsure. The narrator also contemplates this act, but doesn't go through with it. Her father did this too, which did leave you wondering whether the narrator was imprinting her past onto Ernessa, and fantasising about ending her life in the same way.

The Mr. Quin stories have lovers in dire straits as an integral part of the premise; consequently a disproportionate number of them include somebody admitting, explicitly or tacitly, that when Mr. Quin took a hand in their problem they were this close to ending it all.

Brought up in one Doctor Who Expanded Universe novel.
