Should grief be treated like depression? from CNN

Editor's note: Dr. Charles Raison, CNNhealth's mental health expert, is an associate professor of psychiatry at the University of Arizona in Tucson.

(CNN) -- I am starting to think that there are no answers to the issues most worth writing about, at least in psychiatry.

Consider the following scenario: A woman who has been mostly happy in her marriage for 30 years comes home to find her husband dead on the floor, the victim of a heart attack.

At first, she is numb with shock. Slowly, as the days pass, she becomes more and more upset. She cries at any mention of her husband. She can't sleep. She can't eat. Nothing seems worth doing, and even if it was, she wouldn't be able to concentrate enough to get it done.
