"Survivors are basically reliving this experience of surrendering control, they're chasing this need to retell their story on their terms constantly throughout their lives."
As well as this, Grace said she also wanted to work towards breaking down the myth that survivors have to be seen as anything other than a "normal" human being.
"Like, not defined by any experience, they're not defined by their trauma, and there's no such thing as a perfect victim."
