For anyone experiencing extreme guilt, grief, loss, betrayal, doubt, loneliness, depression, despair, obsession, addiction, anger, fear, angst or anxiety. The book goes through every one of these topics in great detail. It explains their causes, symptoms, and ways of overcoming them. It explains the opportunity for growth that is inherent in our struggles, providing inspiration and hope when it is most needed. I will warn that the author uses some vocabulary that non-psychologists won't know. Just keep your dictionary handy.
