The Kübler-Ross Model, developed by psychiatrist Elisabeth Kübler-Ross, outlines five stages of grief that individuals may experience when facing loss or trauma. These stages are denial, anger, bargaining, depression, and acceptance. The model suggests that people may not go through these stages in a linear order and can revisit stages multiple times. Each stage represents a different emotional response to loss. In denial, individuals may refuse to accept the reality of the situation. Anger involves feelings of frustration and helplessness, while bargaining is an attempt to negotiate a way out of the distress. Depression reflects deep sadness, and finally, acceptance signifies coming to terms with the loss.
