Answer:
Based on Erikson's theory, Lily may experience feelings of despair and bitterness.
Step-by-step explanation:
Erikson's psycho-social theory states that we experience eight major stages of development over our lifespan. At each stage, there would be a crisis or task for us to resolve. This theory explains the reason why we are easily motivated by the need to achieve competence in certain areas of our lives.
In Lilly's case, having realized that over the years her life had been fruitless and miserable would make her to develop a sense of despair and bitterness feelings. She might have gone through a lot of challenges and moments during two or more of her developmental stages.
