The Kübler-Ross Model, also known as the five stages of grief, outlines the emotional responses people experience when facing loss or terminal illness. The five stages are denial, anger, bargaining, depression, and acceptance. This model helps individuals understand their feelings and navigate the grieving process. Developed by psychiatrist Elisabeth Kübler-Ross in the 1960s, the model emphasizes that these stages are not linear; people may experience them in different orders or revisit stages multiple times. It serves as a framework for understanding the complex emotions associated with grief and loss.
