About grief

Grief is the response to the loss of something deemed important, in particular the death of a person or animal to which a bond or affection was formed. Although conventionally focused on the emotional response to loss, grief also has physical, cognitive, behavioral, social, cultural, spiritual, political and philosophical dimensions. While the terms are often used interchangeably, bereavement refers to the state of loss, while grief is the reaction to that loss.
