Marbles: Mania, Depression, Michelangelo and Me Paperback / softback

Shortly before her thirtieth birthday, Forney was diagnosed with bipolar disorder. Suffering from (but enjoying) extreme mania, and terrified that medication would cause her to lose creativity, she began a long struggle over many years to find mental stability while retaining her creativity.

Searching to make sense of the popular idea of the 'crazy artist', she finds inspiration from the lives and work of other artists and writers who suffered from mood disorders, including Vincent van Gogh, Georgia O'Keeffe, William Styron, and Sylvia Plath.

She also researches the clinical aspects of bipolar disorder, including the strengths and limitations of various treatments and medications, and what studies tell us about the conundrum of attempting to "cure" an otherwise brilliant mind. Darkly funny and intensely personal, Forney's memoir provides a humorous but authentic glimpse into the effects of a mood disorder on an artist's work, as she shares her own story through black-and-white graphic images and prose.
