If death is not discussed out loud, maybe it won't happen. Death is a sign of human failure. Death is God's revenge on man. You are always a loser in death. No purpose can be served by a death.
Death is the ultimate revenge.
Deal with your denial of the reality of death and the reality of the loss it brings. Cease the bargaining behavior being used to deny the reality of death and the reality of the resulting loss. Work out your anger over the death and the resulting loss. Handle the despair and depression resulting from the death and the resulting loss. Let go of the person, event, or object in death and face the resulting loss.
