Stress consumes doctor within (7)
I believe the answer is:
amongst
'within' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'stress consumes doctor' is the wordplay.
'stress' becomes 'angst' (I can't justify this - if you can you should give a lot more credence to this answer).
'consumes' means one lot of letters goes inside another.
'doctor' becomes 'mo' (medical officer).
'angst' going around 'mo' is 'AMONGST'.
Can you help me to learn more?
(Other definitions for amongst that I've seen before include "In the middle of two or more" , "Having been absorbed, perhaps" , "Famous novel by John McGahern: '... Women'" , "Within the group of" , "Surrounded by" .)
