Which client statement indicates their mental state is unchanged?

The statement "I am not ready to talk about the war" suggests that the client is maintaining their current mental state rather than showing progress or change. This reluctance to discuss a traumatic experience can indicate that the individual is still grappling with issues related to the event, possibly indicating a level of distress or avoidance that has not shifted. In contrast, the other statements, while potentially reflective of a range of feelings or experiences, imply some degree of change: taking medication regularly suggests a commitment to treatment, reporting increased anxiety indicates a shift in emotional state, and expressing that sleep has improved suggests a positive change in well-being. Thus, the statement about not being ready to engage in conversation reflects stability in their mental state, indicating no progression towards processing or coping with their trauma.
