Are you worried that you are too shy or constantly doubt everything? Are you having trouble sleeping because you're worried about your job, health, or relationships? Do you have a fear of heights or have a panic attack when you get behind the wheel of a car? The fact is that anxiety is based on irrational beliefs that make you vulnerable and can lead to depression, says psychotherapist David Burns, author of the international bestseller Mood Therapy and one of the founders of cognitive behavioral therapy. In his new book, he suggests 40 simple, effective techniques to help you get to the bottom of your worries, cope with negative thoughts, and overcome your fears. Dr. Burns also shares research on medications commonly prescribed for depression and explains why they can sometimes do more harm than good. .
