there were not many mainstream movies specifically dealing with generalized anxiety disorder (GAD). However, the film industry is continually evolving, and new movies might have been released since then. Here are a couple of films that were known to address anxiety disorders, including GAD:
"Silver Linings Playbook" (2012) - Directed by David O. Russell, this movie revolves around a man named Pat Solitano, played by Bradley Cooper, who suffers from bipolar disorder and anxiety. The film explores his struggles with mental health as he tries to rebuild his life after being released from a mental health institution. Jennifer Lawrence also stars in this critically acclaimed film, and her character Tiffany Maxwell has her own mental health challenges.
"Prozac Nation" (2001) - Based on Elizabeth Wurtzel's memoir, this movie delves into the life of a young woman named Elizabeth, portrayed by Christina Ricci, who battles depression and anxiety. It explores her experiences with mental health treatment and her journey to find stability and understanding.
It's worth mentioning that while some films may touch on anxiety disorders, they might not always explicitly name or focus on generalized anxiety disorder. Sometimes, characters in movies may exhibit symptoms of anxiety without a specific diagnosis being mentioned. Also, since the film industry is constantly producing new content, there might be more recent movies that address GAD or anxiety-related themes. I recommend checking more recent sources for up-to-date information on movies released after 2021.
