Brené Brown: Beginning with the two Ted Talks, The Power of Vunerability and Listening to Shame, Brown has become a very well-known inspirational speaker and author of several books, all of which I would recommend. She also has online workshops (with homework!) which I have followed and found very helpful and insightful.
Byron Kati: Her first book, Loving What Is, incorporates cognitive behavioral therapy in a unique and confrontational manner. If you explore her website, thework.com, you will find the four questions she asks that have defined her approach.
Anxiety
The Worry Trick: How Your Brain Tricks You into Expecting the Worst and What You Can Do About It (Carbonell) I have read many books about worry and anxiety, and the way the author is able to explain the anxious brain, with humor and doable coping techniques, is impressive.
The Anxious Brain (Wehrenberg)
The Mindfulness Workbook for OCD (Hershfield and Corboy)
Depression
I Don’t Want To Talk About It: Overcoming the Secret Legacy of Male Depression (Real)
Anger
Anger Kills (Williams and Williams) A comprehensive book explaining how anger affects the body. The Hostility Roadmap with Strategies (page 68) is especially helpful.
Trauma, Grief, and Loss
David Kessler has written several books about this subject. He also has a very helpful website, Grief.com
The Body Keeps Score. Brain, Mind, and Body in the Healing of Trauma (van der Kolk)
Getting Past Your Past , Take Control of Your Life with Self-Help Techniques (Shapiro)
As a wise person once said at a conference, “Anxiety is a breathing disorder”. This exercise is one of the many breathing techniques that you can use. I find this one helpful and easy to follow.
