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.

Rasmussen's model of grief operates on the assumption of psychological resilience, echoing the theories introduced by George Bonanno, a professor of clinical psychology at the Teachers College of Columbia University. Her theories conflict with popularized concepts of grief stemming from the 1917 and 1969 publications of "Mourning and Melancholia" and "On Death and Dying" by Sigmund Freud and Elizabeth Kübler-Ross, respectively. The defining characteristic of the model proposed by "Second Firsts" is the view of loss as a catalyst for change and self-growth.
