Jill is a senior in high school. All through her academic career, she has made good grades and has never engaged in delinquent acts. Two months prior to graduation, Jill's mother was in a car accident. A man under the influence of alcohol ran a red light and crashed into Jill's mother's car, killing her on impact. Jill was close to her mother, and her death strongly affected Jill's behavior. She began staying out late; her grades started slipping, and she began drinking alcohol. What negative affective state is Jill experiencing?
