Reddit mentions of The Drowned World

I recommend reading JG Ballard's "Ecocide" trilogy: The Drowned World, The Drought and The Crystal World. Also worth checking out short stories: The Terminal Beach and The Voices Of Time come to mind.

These books, written 50 years ago, were not only among the first to explore the gross effects of ecological collapse, but we the first to concentrate on the psychological and emotional effects. Not just how we'd cope politically or what detailed strategies would evolve, but how we'd deal with it in our heads. What kind of dreams we'd have when the waking world had itself been transformed into a surreal and nightmarish landscape, how we would think when society was collapsing all around us.

He makes for disturbing reading, and he's certainly not "woke" (Horrible racism in particular abounds in The Drowned World), let alone hopeful in the conventional sense - but there's something in the way his characters accept their new lives that we can use - adopting that detachment and almost Buddhist calm has the potential to save your life.

On a personal note: Even if you don't think your life is worth saving, I guarantee that someone, somewhere, feels otherwise. Even if you haven't met them yet. We have a duty to go on living - partly to others, and partly to our future selves. You can always kill yourself later.
