Documents revealing life gone wrong (4)
I believe the answer is:
file
'documents' is the definition.
(file can mean a collection of documents)
'life gone wrong' is the wordplay.
'gone wrong' is an anagram indicator.
'life' anagrammed gives 'FILE'.
'revealing' acts as a link.
(Other definitions for file that I've seen before include "Smoothing tool - orderly batch of documents" , "Folder; rasp" , "Dossier; line of people" , "Tool for sawing through metal" , "Set of papers" .)
