Two crashes, one in which she broke her arm in October and another in which she sustained a concussion in December, seemed to take away the control, the multitasking, that Catlin had always prized. In January, she attempted suicide for the first time and was clearly a different person to her family. “She was not the Kelly that we knew,” her father said. “She spoke like a robot. We could get her to talk, but we wondered, ‘what has happened to our Kelly?’

She also suffered from headaches and light sensitivity. “She had written this lengthy email [to her family in January] and said her thoughts were racing all the time,” Christine Catlin said. “She was suicidal, her thinking was really dark, and she had taken to nihilism. We called police the moment we got the email and they got there in time to save her that time [from suicide].”
