Vemödalen - the frustration of photographing something amazing when thousands of identical photos already exist - the same sunset, the same waterfall, the same curve of a hip, the same closeup of an eye - which can turn a unique subject into something hollow and pulpy and cheap, like a mass-produced piece of furniture you happen to have assembled yourself.
-----------------
In case you are wondering, the word vemödalen is a part of The Dictionary of Obscure Sorrows - a compendium of invented words written by John Koenig. Each original definition aims to fill a hole in the language - to give a name to emotions we all might experience but don’t yet have a word for.
