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.
Breakup
A natural effect of the loss of a relationship that an individual had hoped to keep is grief, because the desire to keep relationships intact despite problems and complications is a natural human desire. This results in individuals undergoing a breakup displaying grief reactions that include symptoms like sleeplessness, depression, and thoughts about suicide. This tendency to express grief and depression is so prevalent that researchers point to it being a significant contributor to the first onset of major depressive disorder in young adults.
