An identity crisis. Yeah it’s not a fun thing to go through. Someday you’ll realise that you don’t even know who you are anymore and begin to doubt your entire personality. Our main character Catherine goes through one of these after her father dies. She begins to think she’ll turn out with the mental illness of her father and she begins to think that she doesn’t fit in the field of mathematics and science like her father because she is a woman. Proof is a play reminding us to take a step back and look at who we are.
