Woman emphasised being upset (10)
I believe the answer is:
distressed
'being upset' is the definition.
(I've seen this in another clue)
'woman emphasised' is the wordplay.
'woman' becomes 'di' (short for Diana).
'emphasised' becomes 'stressed' ('stress' can be a synonym of 'emphasize').
'di'+'stressed'='DISTRESSED'
(Other definitions for distressed that I've seen before include "like Samson when deprived of his strength?" , "In deep pain or sorrow" , "Anxious" , "Upset; deliberately aged" , "in anguish?" .)
