"Everyone feels depressed at some point in their life," said clinical psychologist Bruce Cannon. "If anybody says that they have never been depressed they are one of two things; they're either fairly young or they lying."
Cannon says it's normal to feel sad from time to time but a depressive illness occurs when these feelings interfere with everyday life. The National Institute for Mental Illness reported that 20 million, or about 9.5 percent of Americans, suffer from a depressive illness each year.
