HappyTyme (TM) is an unfinished fanfic by J Osako. Daria is sent to therapy after a series of increasingly morbid jokes and learns there are plans to put her on antidepressants - at which point the story ends/
It was originally written on the 29th of March, 1998, and as such is the oldest known Daria fanfic to still be online!
