Quiet, depressed (7)
I believe the answer is:
subdued
I believe this is a double definition.
'quiet' is the first definition.
(I know this)
'depressed' is the second definition.
(thesaurus)
(Other definitions for subdued that I've seen before include "'Restrained, low-key (7)'" , "Quietened, brought under control" , "Quieted and brought under control" , "Chastened" , "reserved" .)
