According to the model of the five stages of grief, or the Kübler-Ross model, those experiencing sudden grief following an abrupt realization (shock) go through five emotions: denial, anger, bargaining, depression, and acceptance.
Critics of the model have warned against using it too literally.[1]
Introduced as "The Five Stages of Death" by Swiss-American psychiatrist Elisabeth Kübler-Ross in 1969,[2] this model has been known by various names, including "The Five Stages of Loss",[3] "The Kübler-Ross Model",[4] the "Kübler-Ross Grief Cycle",[5] the "Grief Cycle",[6] "The Seven Stages of Grief",[7] and the Kübler-Ross Change Curve".[8][9]
