Answer:
Reorganization.
Explanation:
The reorganization stage is characterized by being the phase in which the mourner begins to understand how much their life is changed, that their old life is gone and begins to accept the new "normal". They begin to accept the positive aspects of their life after their loss, and start to have more energy for activities and hobbies.
