lyssamania

n. the irrational fear that someone you know is angry at you, that as soon as you wander into the room, you'll be faced with a barrage of questions that gradually escalates into a frenzy of outrage, for reasons that you don't understand.

In Ancient Greek mythology, the Maniae are spirits who personified insanity, along with their sister Lyssa, who was known for erupting into rages. Pronounced "lis-uh-mey-nee-uh."
