An 80-year-old woman who lives alone has begun calling friends and complaining in an exaggerated
fashion about minor aches and pains. Her physician found no significant medical problems. Over the course of a month, she obtained a number of prescriptions for pain medication, none of which seemed to be effective. Friends counseled her that aches are a normal part of life for the elderly and tried unsuccessfully to involve her in activities. She often suggested that she would be better off dead, to which one friend responded "Well, perhaps. It would get you out of your misery.". As she became increasingly "needy" and demanding of attention, friends agreed that her behavior made them uncomfortable and began to call and visit less. The woman took four pain pills and called a neighbor, saying she had overdosed. After medical clearance, the client will be monitored at the mental health clinic.
