Distressed, having overturned (5)
I believe the answer is:
upset
I believe this clue is a double definition.
'distressed' is the first definition.
(I know that distressed can be written as upset)
'overturned' is the second definition.
(I know that overturned can be written as upset)
'having' is the link.
(Other definitions for upset that I've seen before include "Overturn, tip over" , "Disturb the balance or stability of" , "Disturbed or inverted" , "Sad" , "Surprise win" .)
