Anticipatory grief
The five stages namely, denial, anger, bargaining, depression, and acceptance proposed by Elisabeth Kübler-Ross in her model of grief describe the process by which people undergo after a loss. Anxiety, dread, guilt, helplessness, hopelessness, and feelings of being overwhelmed are also common. However, it is important to note that anticipatory grief is not simply normal grief begun earlier.
Death education
All of these are defense lines to try and protect us from the reality of pain in a lost one.
The fourth stage is depression. In this stage there can be two different types of depression that you deal with. The first type of depression can be a more quiet and private feeling. The second type of depression is the kind where sadness and regret overtake your body and become the predominate factors in your life.
The fifth and final stage is acceptance. This stage does not always reach everyone but for the people who actually get it should consider this stage as a gift. It does not mean that you will not be sad anymore but it does mean that there is going to be some kind of peace that you are able to reach with the loved one that died.
