Heartache as pride shattered (7)
I believe the answer is:
'heartache' is the definition.
(I've seen this in another clue)
'as pride shattered' is the wordplay.
'shattered' is an anagram indicator.
'aspride' anagrammed gives 'DESPAIR'.
(Other definitions for despair that I've seen before include "Total loss of hope" , "Misery" , "The feeling that nothing will turn out well" , "Feeling of hopelessness" , "Lose heart" .)
