grief can't be defined. grief simply is. or yes. grief can be defined.

Stephen R. Shuter and Sindey Zisook try to do so by stating that "grief comprises the myriad psychological, physiologic, and behavioral responses which accompany the human awareness of an irrevocable loss, such as a pending or actual loss of a close friend or relative. It is an extraordinarily powerful emotion." grief is a powerful emotion. grief is a powerful emotion.
