In addition to numbness, loneliness, and emptiness, grieving can cause uncertainty, deep and continuous sadness, as well as a lack of energy which used to bring you joy. The five phases are denial, anger, bargaining, depression, and acceptance. They are generally discussed as if they occur in a sequential manner, with the individual moving from one stage to the next. Acceptance is the final phase of the grieving process. People begin to come to terms with their own mortality, the mortality of a beloved one, or perhaps the circumstances that led a devastating loss during this final stage of grief. This stage appears to have the most changeable nature of all the stages, as it is so dependent on the individual's state of mind.
