In her 1969 book, On Death and Dying, Swiss-born psychiatrist Elizabeth Kubler-Ross outlined the five stages of grief of someone who is dying:

• Denial and isolation: “This is not happening to me.” 

• Bargaining: “Just let me live to see my son graduate.”

• Depression: “I can’t bear to face going through this, putting my family through this.”

• Acceptance: “I’m ready, I don’t want to struggle anymore.”

The list was praised and criticized by grief experts. Some said the stages got people expressing their emotions; others said the stages were too rigid.
