As someone who has struggled with depression for over half my life, I have read many different books on the subject. I have found that books on depression (with a few exceptions) tend to fall in one of 2 catagories.
First, there are books that deal strictly with the medical aspects of depression. Medication, brain chemistry etc. This is very helpful and necessary, but these books typically don't discuss the spiritual aspect of depression. Even sometimes, if it is a Christian book.
On the opposite end of the spectrum are those books which say that depression is ONLY a spiritual problem. Authors of these types of books typically believe that there is no physiological basis for depression, no Christian should take medication and that faith alone can heal someone with depression. If someone is not healed of depression, it's their own fault. In my opinion, books that take this view do more harm than good. A person with serious depression is already overwhelmed and struggling. These types of books are like kicking someone who is already down.
Fortunately, this book avoids both extremes. Fawcett correctly believes that depression is mental, physical, and spiritual. She doesn't overemphasize any particular one, rather focuses on all three and shows how they contribute to depression and how to treat each aspect. This book focuses on medication and brain chemistry, but also on spiritual aspects of depression as well. I have come to believe that depression is physiological, mental, and spiritual. Anyone who has ever been on medication for depression will tell you that it is not a cure-all. It's not a magic pill. But I strongly believe that a person can be on medication and still have strong faith and trust in God. It can be both/and, not either/or. Depression is an incredibly complex illness, with a variety of causes which can include environmental, situational, and genetic predisposition. This book also refutes some of the common myths about depression and helps the reader understand why a person with depression acts and thinks the way they do. The truth of the matter is that someone who has never experienced serious depression themselves, cannot possible know what it's like. But this book helps pull back the curtain and gives the reader a look into the thoughts, feelings, struggles, and fears of a person with serious depression. Things that can be extremely difficult to put into words, especially to someone who has never struggled with depression.
I highly recommend this book. Both to people who struggle with depression themselves, and also for people who are struggling how to relate to and support and friend or loved one with serious depression. In my humble opinion, this is one of the best books out there on depression. Even though it is written from a Christian perspective, I think even non-believers would benefit from the insights and wisdom of this book.
