She and her children have recently relocated from an urban neighborhood to a rural town to care for her parents, Robert and Susan. The move involved a job change for Elizabeth, a change in schools for the children, and an increased distance from the children’s father Chris. Robert is a 72-year-old Methodist minister who recently suffered a stroke, leaving him with diminished motor function of his left side and difficulty swallowing. Susan is 68 years old and suffers from fibromyalgia, limiting her ability to assist with the daily care of her husband. She has experienced an increase in generalized pain, difficulty sleeping, and worsening fatigue since her husband’s stroke.
