This is one of the books I recommend most often. It is a good solid self-help book that can be applied to many difficulties and situations. Russ is an Australian GP turned therapist. His book explores the principles of Acceptance and Commitment Therapy (ACT) and how to use these to assist you to work through whatever issues you may be facing. It talks about the role of thinking in the pain we experience. Equally, it emphasises the importance of living a rich and meaningful life as a means of mitigating pain. This is an easy to read and digest book. Its relatively short chapters allow you to dive in for a bit, think about what you’ve read and do the exercises! Then come back for more when you are ready. Russ has written several other books and his website https://www.actmindfully.com.au contains other helpful resources. This book is a really good place to start.
