What is the author's tone in Wasted: A Memoir of Anorexia and Bulimia by Marya Hornbacher?

The tone of Marya's book is painfully honest. She writes at one point that she finds it very difficult to write her story. Her struggle with her eating disorder, as well as the emotions and circumstances that initiate the disorder, is very personal and very private. Writing out these feelings in a medium so that others can read about them is both painful and tough. Even through the separation of time, Marya manages to capture the essence of her feelings during the time of which she is writing. She shows her feelings of distaste for and fear of her habit of bulimia. She also portrays the fear she feels as a child and the rebellion she feels as a young teen.
