Based on the real-life diaries of Rae Earl, My Mad Fat Diary is a comedy-drama set in mid-90s England, following the life of Rae, a 16-year-old music-lover, who struggles with body image and mental health issues.
Rae ends up back in the same hospital where everything began. She is adamant that she is staying despite what the doctors say. Kester pays her a visit who still believes that Rae is ready to end therapy despite the setbacks and she finds the strength to return to her old life in Stamford.
Rae takes some drastic action that could ruin her future after Chloe's parents ban her from seeing their daughter in hospital. As Rae attempts to get things back on track, her A-levels and relationship with Finn are left hanging in the balance.
