One traipsed around in torment (11)
I believe the answer is:
desperation
'torment' is the definition.
'one traipsed around' is the wordplay.
'around' is an anagram indicator.
'one'+'traipsed'='onetraipsed'
'onetraipsed' with letters rearranged gives 'DESPERATION'.
'in' is the link.
(Other definitions for desperation that I've seen before include "Abject hopelessness" , "A state without hope" , "State of hopelessness" , "Complete lack of hope" , "'Torment'" .)
