I recently gotten my hands on a wonderful book by Hilary Jacobs Hendel called:
It's Not Always Depression: Listen to the Body. Discover Core Emotions. Connect to Your Authentic Self.
Hilary is has had an interesting career - trained as a dentist, she re-trained to become a psychotherapist - simultaneously studying to be a classical psychoanalyst and an emotion-focused psychotherapist.
In this book, she presents the core of her method to help her patients truly change their stuck emotional patterns such as chronic depression, anxiety, anger and problems experiencing emotions (a.k.a. feeling nothing).
She calls it The Change Triangle. (Those in the know might know it by it's technical name: The Triangle Of Conflict). This is a useful map and tool distilling the insights from psychoanalysis, emotion theory and the clinical experience of many psychotherapists.
I've found it to be extremely powerful in helping some of my clients get to very deep levels of their emotions and to transform these emotions. As a result of this work (Hilary calls it Working the Triangle), some of my clients have (to my pleasant excitement), arrived at a deep clear state of calm, compassion, curiosity and clarity. To be honest, this is the deepest kind of effect my work has had on anyone.
