Misery is a state of deep unhappiness or discomfort. It's not dropping your ice cream cone. It's having a hairy monster steal your ice cream cone, eat it in one bite, and then kidnap you and carry you off to his cave.
Misery describes a miserable situation and a miserable feeling. Waiting four hours in the hot sun for a concert you don't want to see and can't afford? That's misery. The only way to survive is to bring a friend who hates the band as much as you––because misery loves company.
