I really don't want to vote Karen, if I voted no I'd feel that I was being negative, and if I voted yes and your story didn't sell I'd feel that I advised you incorrectly. 

Let me say this, there is a hell of a lot of hard work involved in writing a story about your life (biography), and as you have correctly said it's been done before.

However there is a book over here called "Becoming Drusilla" please read it, and see that it was not an autobiographical tale, it was written by Dru's friend Richard Beard, who knew Dru as Andrew prior to transition. He at first had a hard time with accepting Dru, after all she was very much mechanically minded, and the type of person - similar to myself in fact - that can fix most things. They used to go on long walks in the countryside backpacking with lightweight tents, so in the book they did it again but this time with Dru fully transitioned......

I doubt that has been done in the US, and I doubt that many US citizens will have read "Becoming Drusilla", so perhaps doing your story from a similar second party perspective might work?

Cheers,
