“As the new year began, [Patricia Highsmith] felt completely paralysed, incapable of reading or picking up the phone. 'I can feel my grip loosening on my self,' she wrote. 'It is like strength failing in the hand that holds me above an abyss.' She wished there was a more awful-sounding word for what she was feeling than simply 'depression'. She wanted to die, she said, but then realised that the best course of action would be to endure the wretchedness until it passed. Her wish was, 'Not to die, but not to exist, simply, until this is over'.”
