Gloomy doctor got up (6)
I believe the answer is:
morose
'gloomy' is the definition.
(morose means gloomy or sad)
'doctor got up' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'got up' becomes 'rose' (past tense of 'raise').
'mo'+'rose'='MOROSE'
(Other definitions for morose that I've seen before include "in gloomy mood" , "Sullen, crabby" , "Gloomy and unsociable" , "Lugubrious" , "Sullen or glum." .)
