Maureen facing gym gets to be depressed (4)
I believe the answer is:
mope
'to be depressed' is the definition.
'maureen facing gym' is the wordplay.
'maureen' becomes 'mo' (I've seen this in other clues).
'facing' says to put letters next to each other.
'gym' becomes 'pe'.
'mo'+'pe'='MOPE'
'gets' is the link.
(Other definitions for mope that I've seen before include "Hang around being miserable" , "Move around slowly and aimlessly" , "Wander round gloomily" , "Poem (anag.)" , "Sulk; mooch" .)
