Out-of-control anxiety can be disabling -- limiting where sufferers can go and what they can do, impeding life goals, and causing frightening physical symptoms. Yet effective treatments are available, and cognitive behavioral therapy -- developed and tested over more than 25 years by pioneering clinician/researcher Aaron T. Beck -- is one of the best. Now Dr. Beck and fellow anxiety expert David A. Clark provide a complete, accessible, empowering workbook for anxiety sufferers who want to take back their lives. A wealth of stories, self-assessment tools, worksheets, and exercises help readers identify their own anxiety triggers and challenge the thoughts and beliefs that lead to distress. By learning to think differently, readers can truly loosen anxiety's grip -- one manageable step at a time.
