Thinking one has an illness one does not actually have.
A Frenchman, a German and a Jew walk into a bar. "I'm tired and thirsty," says the Frenchman. "I must have wine." "I'm tired and thirsty," says the German. "I must have beer." "I'm tired and thirsty," says the Jew. "I must have diabetes."I *cought* can't Describe Hypochondria Here. I, I think I have Rigelian Fever. I can tell because I blew my nose three times today! This trope is the tendency for people to often, if not outright chronically, think they are coming down with diseases based on vague symptoms. This is usually Played for Laughs in fiction, showing these people as whiny, lazy, and/or paranoid. This is especially common among Jews making fun of themselves for being like this. This can be Played for Drama, if someone is actually debilitated by this, but it's very rare. These days, using the internet for self diagnosis has become a new tool for this trope. A Sickly Neurotic Geek is more likely to be this than actually sickly. A Super Trope to Induced Hypochondria. Compare Playing Sick (when characters know they aren't actually sick), You Don't Want to Catch This (which is faking an illness for other reasons), Mistaken for Dying, Jewish Complaining (which often involves something that might get them sick).
