Laura Dockrill describes her frightening experience of post partum psychosis after giving birth to her son. She calls for a wider conversation about risks to parental mental health and for help to be open to everyone. "This almost invisible illness was an assassin. An apparition that nobody else could see." "Silence only inflames the symptoms, the stigma and creates an ideal culture for a mental illness to thrive. Shame, judgment and fear follow fast in the wake and it's a perfect storm, one that can unfortunately end in tragedy. But it doesn't have to. Post-Partum Psychosis is treatable." Laura Dockrill is an award winning author, illustrator and performance poet. "What Have I Done?" is her memoir on motherhood and mental health. Presenter: Olly Mann Producer: Sheila Cook
