Final answer:
The client's feelings of worthlessness and degradation are best understood through the lens of Psychoanalysis, which aims to resolve internal psychological conflicts and uncover the influence of the unconscious mind on behavior.
Step-by-step explanation:
The client's unconscious feelings of worthlessness and degradation relate to Psychoanalysis, a psychological theory and therapy technique pioneered by Sigmund Freud. The main premise of psychoanalysis is that the unconscious mind harbors thoughts, feelings, and memories that are outside our conscious awareness but greatly influence our behaviors and emotions.
Freud developed therapeutic techniques such as dream analysis and free association to bring these unconscious elements to consciousness, thereby helping individuals to address their psychological distress. He proposed a structural model of the mind, consisting of the id, ego, and superego, which are in constant conflict and shape our feelings and behavior.
