The memoirs I've read usually start out with a bang of an intense episode and then start with the author's childhood re: bipolar. Some are just a time line of each episode and/or hospitalization (like "Madness"by Marya Hornbacher) and some tie in other parts of their lives along with the bipolar aspect (like "Gorilla and the Bird"). Actually, Terri Cheney, author of "Manic", wrote a whole book about her childhood being bipolar called "The Dark Side of Innocence". So whatever your book turns out to be, I think I'd see it as a bipolar memoir- with an added bonus! (Like "Gorilla and the Bird").
