I have depression, and the way I often describe that is to explain that there are times when my brain doesn't like me. It's very hard to explain that feeling of part of you explaining to you all the ways you're worthless, but I recognised it in this account of mental illness and the effect it can have on your life. What this book captures is the way in which something that from the outside seems absurd can become entirely logical to you because something inside you is telling you that's how it should be. This book manages to combine oh-my-God terrifying and laugh-out-loud funny, often in the same paragraph about the same event.
