'The first of its kind, this self-help book will offer guidance, help and solace to the many sufferers of depersonalization disorder.' Daphne Simeon, Depersonalisation and Dissociation Program, Mount Sinai School of Medicine, New York Depersonalization disorder can make you feel detached from life and many people describe feeling 'emotionally numb', unreal or even as if their body doesn't belong to them. It can be a symptom of another problem such as anxiety, depression, post-traumatic stress disorder and, particularly, of panic disorder, or of an illness like epilepsy or migraine. It can also occur in its own right and/or as a side effect of certain drugs.
