Actress Tuppence Middleton has Obsessive Compulsive Disorder (OCD). It's not something she's really talked about before, except with a therapist. That is, until now. In this series, she's on a mission to find out more about the disorder - and herself - and to bust some myths along the way.
Today, she talks to clinical psychologist Dr Gazal Jones. What's going on in the brain? How does it affect people differently? And what's the best way to get treatment?
