Grief is the reaction to loss, and any kind of loss can trigger grief. People grieve for the loss of someone they love, but they also grieve for the loss of independence, usefulness, cognitive functioning, and physical abilities. Grief is also a lifelong process: a journey rather than a disease that is cured. It changes over time to deal with different kinds of losses. It is an experience that is intellectual, physical, spiritual, and emotional. It is affected by the person’s culture, support system, religious beliefs, and a host of other factors.
