There is a new book out that gives self-help techniques that have been researched and are taught by clinicians. The book is called:
Getting Past Your Past: Take Control of Your Life with Self-Help Techniques from EMDR Therapy. The techniques include ones that can help deal with stress, get rid of negative thoughts and feelings and also ones that are used to improve relationships and social interactions. There are also exercises and techniques to identify the reasons for different issues and problems. I suggest checking out the reviews on Amazon.
