In his 2012 book Time Cure , psychologist Philip Zimbardo introduced a groundbreaking therapeutic approach for PTSD sufferers, co-developed with Rosemary Sword. "Time Perspective Therapy" shifts mental focus from the past to the present, and from negative to positive events, helping anyone achieve a more balanced view of life. Featuring real-life stories, this book describes how TPT helps people living with depression, anxiety or stress to move beyond past negative experiences--from toxic relationships to bullying--toward a more positive future.
