Finished with supporter, doctor died, reproached (9)
I believe the answer is:
upbraided
'reproached' is the definition.
('upbraid' can be a synonym of 'reproach')
'finished with supporter doctor died' is the wordplay.
'finished' becomes 'up' (eg 'time's up' means the time is finished).
'with' indicates putting letters inside.
'supporter' becomes 'bra' (a bra gives support to breasts).
'doctor' is an anagram indicator.
'died' is an anagram of 'ided'.
'bra' inserted within 'ided' is 'braided'.
'up'+'braided'='UPBRAIDED'
(Other definitions for upbraided that I've seen before include "faulted" , "Criticised" , "Admonished" , "Reprimanded" , "Scolded, reproached" .)
