Waiting for a phone call or a message from a prospective lover has uncertainty that can worsen feelings of aloneness.

‘Aversion to aloneness can be treated by habituation similar to a dog phobia’, reports Helen Thomson, ’The Agony of Waiting’, New Scientist, 19 October 2019, p43. Gradual exposure can reduce fear.

Alternatively, throwing yourself into an engrossing task can provide helpful diversion. Aloneness is not a pathological condition.

Robin Williams said ’the worst thing in life is to end up with people who make you feel alone’.

The  Roman philosopher Cicero said that he was never less lonely than when he was alone.
