Distressed, worried (8)
I believe the answer is:
troubled
I believe this is a double definition.
'distressed' is the first definition.
(similar in meaning)
'worried' is the second definition.
(similar in meaning)
(Other definitions for troubled that I've seen before include "Inconvenienced" , "Worried" , "Anxious" , "Disturbed, bothered" , "Bothered, perturbed" .)
