Karen is a college student majoring in biology who feels stressed and anxious due to her busy schedule of school, work, and studying. She often bottles up her feelings because she doesn't have much time to talk to people or feels like she doesn't have someone to listen. Journaling is recommended as a way for Karen to express herself without needing time or artistic talent, and doing it at the same time each day could help reduce her stress even if she only writes one sentence.
