Final answer:
The stages of grief mentioned are Depression, where a patient feels disbelief and sadness, and Acceptance, where one finds peace with the illness.
Step-by-step explanation:
The question refers to two stages described in Elisabeth Kübler-Ross's five-stage model of grief regarding reactions to terminal illness. The first stage mentioned, characterized by disbelief in the illness and feelings of sadness and hopelessness, is known as Depression.
In this stage, a patient might express a desire to be free from pain and may exhibit symptoms of psychological depression. The other stage, where a patient finds peace with the illness, is called Acceptance.
At this stage, patients adjust to the reality of death, regard it as a natural part of life, and may make the most of their remaining time. It's important to note that not everyone goes through these stages in the same order or experiences all of them, and factors like religious beliefs can influence how individuals cope with grief.
