Getting into beer, one good person raving (10)
I believe the answer is:
distraught
'raving' is the definition.
(both can mean distressed)
'getting into beer one good person' is the wordplay.
'getting into' means one lot of letters goes inside another.
'beer' becomes 'draught' (draught beer is a type of beer).
'one' becomes 'I' (Roman numeral).
'good person' becomes 'st' (saint).
'i'+'st'='ist'
'draught' going around 'ist' is 'DISTRAUGHT'.
(Other definitions for distraught that I've seen before include "Beside oneself" , "Grief-stricken" , "At one's wits - end" , "in a state" , "crazy" .)
