Answer:
unconscious mind
Step-by-step explanation:
Unconscious mind: In psychology, the term "unconscious mind" was proposed by one of the most influencing psychologists named Sigmund Freud in the "psychoanalytic theory of personality".
According to Freud, an unconscious mind is described as an individual's reservoir of urges, feelings, memories, and thoughts that are considered as beyond or outside of his or her conscious mind or awareness. Generally, the content of an individual's unconscious mind is considered as unpleasant or unacceptable, for example, feelings of conflict, anxiety, or pain, etc.
In the question above, Freud would suggest that the problem lies with Darla's unconscious mind.
