Self-promotion inbound: I got a full novella out on amazon/kindle called "A Good Ending" that was pretty well received and is inspired by a lot of other novels like "The Road", "A Canticle for Leibowitz", and the Fallout series. Post-Apocalyptic Solitude is a re-telling of the shortest horror story (The Knock) and while it isn't post-apocalyptic per se, Tryps is an apocalyptic one.

As for non-self promoting. I'm sure you're checked out Dogscape and probably googled "creepypasta wiki apocalypse" and got The Insane Apocalypse. Fun fact, creepypasta.org has an apocalyptic category that might suit your needs.

Best of luck with the hunt.
