'Overthinking' is also known as 'worrying' or 'ruminating' and it's a form of anxiety from which many people suffer. Written by psychologist and New Zealand bestselling author Gwendoline Smith, The Book of Overthinking explains in clear and simple language the concepts of positive and negative overthinking, the truth about worry and how to deal with the 'thought viruses' that may be holding you back. With a light, accessible tone and examples of common anxiety inducing situations, she helps you understand the root causes behind the 'what if cycle' and offers powerful strategies for addressing your issues. Based on cognitive behavioural theory, this book will help you in all the key areas of your life - from the personal to relationships and work - providing an essential toolkit to the skills and strategies you need to stop the cycle of worry.
