When she took this teaching position, she had to relocate to a city over four hours away from her family and the house she grew up in. Even though she has made some new friends, Christina still feels disconnected and lonely. She is also concerned about her mother, who has been diagnosed with a serious health condition.For the past month, Christina has felt much worse. She reports feeling very sad and tired most of the time and is having difficulty concentrating at work. She says that she does not have enough energy to accomplish the things she would like to do. She admits to overeating and drinking every evening to “unwind” after school, and is concerned she is sleeping too much on the weekends. She also has very low self-esteem, despite being well-liked at her school and receiving good performance evaluations.Christina describes her life as “heading nowhere” and says that lately she has felt extremely hopeless. She wonders if she will ever feel as happy as she did when she was in college.
