Morituriac 

adj. a person who feels the insomnia-borne jolt of awareness that they will die, that these passing years aren’t just scenes from a dress rehearsal, rounds of an ongoing game, or chapters in a story they'll be told later, but are footprints being lapped by the steadily gathering tide of an unfathomable abyss.

"If you really wanna become a morituriac, read "A Little Life" by Hanya Yanagihara"
