I was hesitant to post a review of this book because people might jump to certain conclusions after hearing I'd read it. But I think this book has enough potential to be helpful to people dealing with mental illness (either in themselves or a family member or friend) that I wanted to publicize it more, on the off chance that I could influence even one person who might be helped by this book to read it.
This book is a vivid and moving portrait of the author's struggle with grief, depression, and suicidality (including a suicide attempt), and also gives a rare in-depth look at her progress in therapy and relationship with her therapist. It's definitely not the most well-written book in the world, which may be off-putting to some, but the author's good intentions--to tell her story and use it to help others--mostly made up for that for me. It's a pretty tough read in spots (it contains vivid depictions of abuse, suicide attempts, substance abuse, etc), so I would hesitate a bit to recommend it to someone who is, e.g., acutely suicidal. But I think it would definitely be helpful to people struggling with depression, people taking care of depressed family members or loved ones, and also those who have acted as a caregiver for the terminally ill (the author's husband died of ALS, and she discusses caring for him and her feelings about his death at length). This book is also required reading in some clinical psychology programs, so would also be of interest to anyone with an interest (career-wise or otherwise) in that field.
Overall, certainly not a book for everyone, but very rewarding if you can stick it out to the end.
