I bought this book for my wife about a year ago. She's manic bipolar and has a hard time dealing with some things. I purchased this book not only to better understand her, but to help her overcome the effects that it has on her. This book has helped both of us so much. We are even closer, as a couple. We are also happy. I now understand how hard it is for her, and I know what to do when she has an attack. I would recommend this book not only to someone suffering from a bipolar disorder, but to someone who wants to understand their friend or loved one, suffering from it.
