I'm conflicted. "Prozac Nation" is probably one of the truest accounts of someone with chronic major depression that I've ever read. It's dark, it's full of self-loathing, and it's narcissistic. The problem with a straight account of chronic major depression is that it's likely to be extremely annoying to read for the mentally healthy. So authentic is the writing that it makes the reader feel a sample of what it is actually like to be with a person who is chronically depressed for a period of time. Most people leave out of frustration. I'm afraid that the same could be said about reading this memoir.
Thoughts on the ending: After reading this book, it's easy to see that Elizabeth Wurtzel is obviously intelligent and, despite coming from a broken home, fairly well-off financially. She's also fundamentally broken emotionally from start to finish. If you're looking for her mental state to progress, you will be disappointed. There is no happy ending. Elizabeth's greatest accomplishment is that she is alive. Her life isn't any better at the end than at the beginning. It's this point that is the hardest to read. It's unsatisfying. The ending is abrupt. But it's also real. This is a real person in this book. Real life is often cruel and unsatisfying.
