She's suffering daily (5)
I believe the answer is:
lydia
'she's' is the definition.
'suffering daily' is the wordplay.
'suffering' is an anagram indicator.
'daily' anagrammed gives 'LYDIA'.
(Other definitions for lydia that I've seen before include "Daily it's a girl's name" , "Girl's name - ancient kingdom in Asia Minor" , "Old kingdom" , "Old country" , "where Croesus was king" .)
