This is a thoughtful up-to-date encyclopaedic handbook by an expert through lived experience who has thoroughly and respectfully researched and reflected on key issues. -- Valerie Sinason, PhD MInstPsychoanal FIPD, Founder and Patron, Clinic for Dissociative Studies This clear, empathetic and accessible work, written with an open mind by someone with lived experience, offers a thorough look at the many ways DID and OSDD are understood and managed. With practical tools for healing and support, it's a valuable resource for people with DID/OSDD, loved ones, professionals and the wider public. -- Anne Lagemaat, expert by experience, founder of DIS is me, an online initiative in the Netherlands about DID/OSDD As someone that was harmed by mental health professionals' misunderstanding and stigma of DID, I feel this book should be mandatory for them. I encourage everyone with DID to have this book by their side. I have felt so validated, and the guidance has provided me with comfort and reassurance. -- Claudia, person with DID As a human and professional psychologist living with DID, my own system of PARTs have waited years for a book like this one.

The information shared with us is delivered in a clear, kind, and compassionate way that few others can offer us as a population of people living with DID. -- Dr. Adrian A.
