Problem: Eight weeks ago, Barbara's father suffered a heart attack. He was in critical condition for two days, but continued to recover and is currently doing well. However, two days after her father's heart attack, Barbara drove herself to the emergency room certain that her symptoms of shorten of breath and chest pain signaled that she too was having a heart attack. The doctor diagnosed her with anxiety and prescribed a limited prescription of diazepam, which Barbara took appropriately. Barbara's symptoms decreased. However, one week later, with no precipitating event, Barbara again suffered shortness of breath and chest pain. After finishing a session with her client, she called her mother for a ride home.
