In the wake of the Covid‐19 pandemic, challenges with adolescent mental health are on the rise, making the need for spaces where teens share their emotions and experiences all the more vital. This single‐case study explores the impact of writing on one young woman's (Celia) mental health during Girl Power, a gender empowerment poetry writing workshop for adolescent girls. Celia's poems, interviews, and discussions illustrate the complexity of the intersections of mental health with friendship, body image, and identity as a girl, revealing the benefits of a supportive community for writing for self and catharsis. This article concludes with practical implications for the healing power of writing both in and out of the classroom.
