Misery writer is tormented (10)
I believe the answer is:
distressed
'is tormented' is the definition.
(thesaurus)
'misery writer' is the wordplay.
'misery' becomes 'distress' (I've seen this before).
'writer' becomes 'ed' (I've seen this in other clues**).
'distress'+'ed'='DISTRESSED'
(Other definitions for distressed that I've seen before include "In deep pain or sorrow" , "Anxious" , "in anguish?" , "Upset; deliberately aged" , "like Samson when deprived of his strength?" .)
