Onism
noun /ˈɒnɪzəm/ — The awareness that you will only ever experience your own life.
Definition
The frustration of being stuck in just one body, inhabiting only one place at a time, while the rest of the world continues without you — all those other lives unlived, all those rooms you'll never sit in.
Beyond the definition
You can read about other countries, other childhoods, other ways of being — but you can only ever live as yourself. Onism names the strange claustrophobia of having only one life to spend.
Origin & history
Coined by John Koenig in The Dictionary of Obscure Sorrows. From Greek 'onos' (donkey) as a symbol of burden, echoing the sense of being trapped within a single existence.
