Grief is the response to a loss, particularly the loss of a loved one. It may also be experienced by the loss of a valued possession, a job, the end of a relationship or a pet. It also follows a diagnosis of a terminal illness like cancer, diabetes or a change in HIV status.
Negative emotions such as sadness, anger or sorrow are associated with grief. Besides the psychological aspect, it also has a bearing on the social, cognitive and physical state of the individual.
