Tristimania is a 2016 book by Jay Griffiths describing her experience of an episode of manic depression that lasted a year. In the book, she uses her training as a writer to make notes, and tells the story of the condition both from the inside and in terms of literary understanding: with etymology, metaphor, mythology, music, and poetry pressed into service to give the reader a picture of the events as she perceived them. The book has been praised by critics for its bravery, and for its ability to connect personal experience to a shareable understanding.
