Stirred (8)
I believe the answer is:
agitated
'stirred' is the definition.
('agitate' can be a synonym of 'stir')
This is the entire clue.
(Other definitions for agitated that I've seen before include "Jittery, hyped up" , "Stirred up, excited" , "On edge, anxious" , "in troubled state" , "Upset (by a stirrer?)" .)
