Finished with turbulent time, getting agitated (11)
I believe the answer is:
overwrought
'agitated' is the definition.
(similar in meaning)
'finished with turbulent time' is the wordplay.
'finished' becomes 'over' (similar in meaning).
'with' becomes 'w' (abbreviation).
'turbulent' becomes 'rough' (synonyms).
'time' becomes 't' (abbreviation).
'over'+'w'+'rough'+'t'='OVERWROUGHT'
'getting' is the link.
(Other definitions for overwrought that I've seen before include "Distraught, worked up" , "Unusually complex" , "Too elaborate; highly strung" , "Nervously excited" .)
