Cаse: A 12-yeаr-оld girl presents with symptоms оf аnxiety. Her parents report she has always been anxious, but her anxiety levels have escalated during this school year. She frequently resists going to school in the morning. Once there, her symptoms often escalate enough to involve the school nurse. They are usually alleviated by telephone contact with her mother. Symptoms also occur on weekends when her mother has to work. The patient has a normal group of friends, but she prefers to be with them at her home rather than elsewhere. She has never slept away from home. She spends a considerable amount of time alone in her room, but she will often come out to "check up" on her mother. Question: What diagnosis best fits the patient's symptoms?
