Mrs. B has been teaching English for the past 12 years. Until this year, she always planned interesting and creative lessons for students with a variety of different activities. This year, the quality of her lessons gradually deteriorated. She began to doubt her ability to motivate students, believing her students found her "boring." In an evaluation, the school principal mentioned that her classes appeared "poorly organized." During the past year she has undergone a variety of life changes, including the death of her 82-year-old father and the departure of her only child for college out of state. She confided in a close friend that she has been feeling overwhelmed and lonely.
