Acceptance and commitment therapy (ACT) is a new, scientifically based psychotherapy that takes a fresh look at why we suffer and even what it means to be mentally healthy. What if pain were a normal, unavoidable part of the human condition, but avoiding or trying to control painful experience were the cause of suffering and long-term problems that can devastate your quality of life? The ACT process hinges on this distinction between pain and suffering. As you work through this book, you'll learn to let go of your struggle against pain, assess your values, and then commit to acting in ways that further those values.
