Why this word is great
HEDONOPHOBIA — [Noun] An irrational fear of pleasure or joy, particularly when others are suffering. From Ancient Greek ἡδονή (hēdonḗ, "pleasure") + -phobia ("fear"), it is guilt crystallized into dread. Unlike "cherophobia" (which shuns happiness itself) or "anhedonia" (which cannot feel it), hedonophobia is the specter of joy as betrayal. It is the untouched birthday cake when a friend mourns, the stifled laughter in a hospital hallway, or the way sunlight feels obscene on a day of collective grief—a quiet conviction that pleasure, in an unjust world, is a debt unpaid.
