Answer:
D.) Empty Nest Syndrome
Step-by-step explanation:
This is an example of what is known as the empty nest syndrome. Empty nest syndrome occurs when children leave home for the first time and parents experience a feeling of grief or loneliness. This most often happens when their children leave to go to university, to be with a partner or to live on their own. This feeling is particularly common in full-time mothers, and can lead to depression or a loss of purpose.
