Because grief obeys its own trajectory, there is no timetable for feelings of pain after loss; nor is it possible to avoid suffering altogether. In fact, attempts to suppress or deny grief are just as likely to prolong the process, while also demanding additional emotional effort.
Stages of grief: Many people expect to experience denial, anger, bargaining, depression, and acceptance, in that order, due to the continuing influence of On Death and Dying, the 1969 book by psychiatrist Elisabeth Kubler-Ross. However, it has been demonstrated that many, if not most, people will not progress through these stages. While some people do experience the stages, and eventually reach acceptance after a loss, grief is now understood to be highly individualized and unpredictable.
