About the Show
“They just thought I was eccentric – but that wasn’t all there was to it.”
Rosie’s Brain is a delightful and heartwarming one-woman musical comedy about a young woman who battles anxiety and OCD. The story follows Rosie from her initial struggles with anxiety to her first day at college. There, she faces a new challenge: a fear of dating so intense she can’t even hold a guy’s hand.
We follow Rosie as she dives into therapy in an attempt to unlock her fear of intimacy and find love. Throughout the ups and downs, Rosie emerges stronger, learning to trust herself despite her diagnoses. This poignant and humorous musical explores the complexities of mental health and the journey toward self-belief and resilience, offering an uplifting performance filled with laughter and heart.
After having performed in the UK, this is the first US performance.
