Coping with losing a loved one is one of life's great difficulties. If you have experienced the pain of mourning, you know that any way to ease the loss is welcomed. While our knowledge and study of grief continues to evolve, it's important to note that not everyone grieves in the same way: We have individual patterns and different outlets for grief. There has also been research on stages of grief—denial, anger, bargaining, depression, acceptance—but people do not always experience these stages in any particular order, nor do they experience every stage. In the worst cases, there are individuals who suffer more severe grief, known as prolonged grief and formerly complicated grief, which can last up to months. This form of grief can pave the way to isolation and chronic loneliness.
