Depressing, gloomy (6)
I believe the answer is:
dismal
I believe this is a double definition.
'depressing' is the first definition.
(I've seen this before)
'gloomy' is the second definition.
(I know that gloomy can be written as dismal)
(Other definitions for dismal that I've seen before include "Gloomy and depressing like winter weather" , "Gloomy, bleak" , "down in the dumps" , "dark" , "Sad, gloomy" .)
