Why do people become depressed or even suicidal? Why do some people feel anxious and fearful of social interactions? Why is it so difficult for us to step out of the shadows after experiencing trauma? Why are some people narcissistic and others have low self-esteem? Why are gambling and drugs addictive? We all have had such unusual experiences at one time or another, whether it's ourselves or our family and friends. Abnormal psychology and behavior are not far away from us, they happen around us.
