Recoil from a psychiatrist (6)
I believe the answer is:
shrink
This clue is a double definition.
'recoil' is the first definition.
(synonyms)
'a psychiatrist' is the second definition.
(informal term for a psychiatrist)
'from' acts as a link.
(Other definitions for shrink that I've seen before include "Decrease - therapist" , "Draw back from the psychiatrist?" , "Diminish" , "Contract, grow smaller" , "Withdraw from" .)
