Final answer:
The stage where people get over the initial shock of a change and recognize its reality is the acceptance stage, the final phase in the Kübler-Ross model of grief.
Step-by-step explanation:
When people get over the initial shock of a change and realize it is going to become a reality, they have reached what is known as the acceptance stage. This stage is part of the Kübler-Ross model, which describes the five stages of grief people often go through in response to a significant change or loss. The stages are denial, anger, bargaining, depression, and finally, acceptance. People experiencing these stages in response to various life events, such as a terminal illness diagnosis or a major life transition, may not experience them in a linear fashion, and not everyone goes through all the stages. Nevertheless, acceptance signifies a turning point where an individual has begun to integrate the new reality into their life.
