Feverish, agitated (6)
I believe the answer is:
hectic
I believe this is a double definition.
'feverish' is the first definition.
(I know that feverish can be written as hectic)
'agitated' is the second definition.
(similar in meaning)
(Other definitions for hectic that I've seen before include "'Excited, flustered or rushed (6)'" , "Frantically busy" , "'Rushed, madly busy (6)'" , "Extremely busy - fevered" , "Agitated and rushed" .)
