I couldn't have articulated this process at the time; I just sort of did it instinctually. But now when I talk about this with my students all the time, it's one of the first things I address in memoir classes - that you have to put it all in because you're writing your way into the ending of your own story. Even if you think you know what the story is, you don't until you write it. If you start leaving things out you could leave out vital organs and not know it.

Being a dominatrix, sticking my foot up people's asses for money, necessitated that I divorce myself from any sort of objective perspective on what I was doing. In order to think about things as a writer you have to objectify your experience. I couldn't have been enacting that experience if I was objectifying it.

I more seriously considered publishing it under a pseudonym than I considered publishing it as fiction. I think the decision to write it as nonfiction happened at the very outset of the process, because the overwhelming impetus for writing this book was to understand what the experience meant, and to override my own reductions and rationalizations, whatever story I had that was not true. It didn't sit well with me and I needed to answer that. That's sort of the reason I write everything.

Children's stories force logic upon the gruesome facts of our lives. They mirror our troubles and submit them to a chain of causality.

I could not kick heroin to save my life, literally, until I started telling my secrets. It was some of the clearest evidence I've ever found of anything. It was the only immediate change in behavior I've ever undergone. I told the most frightening truths, and I was free.

All our stories are part invention - the way we've decided to make sense of what has happened.
