Girl power brings depression (3)
I believe the answer is:
dip
'depression' is the definition.
(dip is a kind of depression)
'girl power' is the wordplay.
'girl' becomes 'di'.
'power' becomes 'p'.
'di'+'p'='DIP'
'brings' is the link.
(Other definitions for dip that I've seen before include "Dunk" , "An informal swim or a downward slope" , "Sink; brief swim" , "Quick swim" , "Thick sauce; brief swim" .)
