I am depressed I feel angry I am at a loss for words I am sick. Ever since I remember myself I try to understand feelings interpret words recognize emotions justify acts; I try to understand human beings. Finally I made a profession out of it. This book comes as a result of my journey through human psychopathology. I want to thank Nikiforos V. Angelopoulos professor of Psychiatry who escorted and guided me through this trip. Most important I wish to thank all my patients who shared their agony and their wisdom with me.
