By the 21st century, loneliness has become ubiquitous. Commentators call it ‘an epidemic’, a condition akin to ‘leprosy’, and a ‘silent plague’ of civilisation. In 2018, the United Kingdom went so far as to appoint a Minister for Loneliness. Yet loneliness is not a universal condition; nor is it a purely visceral, internal experience. It is less a single emotion and more a complex cluster of feelings, composed of anger, grief, fear, anxiety, sadness and shame.
