My first impression was arrogant, apathetic, and wrong. This book demonstrates the real pathology of depression, and for that, it's brilliant. You hear the negative thought processes that people with a depressive disorder experience, the anhedonia, the alienation, the feeling of being lost. "All you can see is the moment you're stuck in," he says, and he's right.
So read this. It'll help you understand, and maybe have a little empathy for the millions of people who suffer from depressive disorders. But maybe be prepared to find the author's tone a little annoying.
Blogging for Books provided me a free review copy of this book... and I still feel kinda 'meh' about it.
