Thanks to Peter da Silva and someone called Disappointed Optimist, I discovered a fine website called The Dictionary of Obscure Sorrows, which is where many of these came from…

1. Énouement

The bittersweetness of having arrived in the future, seeing how things turn out, but not being able to tell your past self.

2. The long dark tea-time of the soul

How Douglas Adams described the failure to think of anything to do on a Sunday afternoon; the wretched boredom of the immortal Wowbagger. Thanks to Ed Rogers.

3. Anticipointment

The sinking feeling when anticipation fails to be the greater part of pleasure. Nominated by Joe Ainsworth.

4. Ellipsism

The sadness that you’ll never know how history turns out.

5. Sonder

The realisation that each passer-by has a life as vivid and complex as your own.

6. Ely

7. Mauerbauer- traurigkeit

The inexplicable urge to push people away, even close friends you like.

8. Zenosyne

The sense that time keeps going faster.

9. Kenopsia

10. Monachopsis
