What is the author's style in Prozac Nation: Young and Depressed in America by Elizabeth Wurtzel?

The perspective of the novel is thoroughly from the point of view of Wurtzel. The reader never receives any other commentary from other individuals throughout the book. For this reason, the reader relates highly to Wurtzel and feels as though they are hearing a story from the point of view of a friend, rather than just an author writing a book. The reader relates to her emotions and events. Since she clearly defines her emotions and why she reacts the way she does (or when she admits that she realizes that she's crazy but cannot control her actions), the novel has more authenticity and clarity.
