A 24-year-old female graduate student presents with three weeks of right leg weakness and gait disturbance that began after a verbal altercation with her academic advisor. Neurological workup including MRI of the brain and spine, nerve conduction studies, and extensive laboratory testing is negative. Neurological examination reveals Hoover's sign, inconsistent weakness on formal testing, and give-way weakness patterns. The neurologist diagnoses functional neurological disorder (conversion disorder) and refers to the PMHNP. The patient becomes tearful and states she is not faking and that her symptoms are real. She has a history of childhood emotional neglect and reports high academic stress. Which treatment plan is most appropriate?
