Tormented, hears sad disturbance (8)
I believe the answer is:
harassed
'tormented' is the definition.
(harassing is a kind of tormenting)
'hears sad disturbance' is the wordplay.
'disturbance' is an anagram indicator.
'hears'+'sad'='hearssad'
'hearssad' with letters rearranged gives 'HARASSED'.
(Other definitions for harassed that I've seen before include "in a state of torment" , "Pestered continually" , "Distraught" , "Plagued" , "Badgered" .)
