Group with trouble worshipping (7)
I believe the answer is:
adoring
'worshipping' is the definition.
(I've seen this before)
'group with trouble' is the wordplay.
'group' becomes 'ring'.
'with' is a charade indicator (letters next to each other).
'trouble' becomes 'ado' (I've seen this before).
'ring' after 'ado' is 'ADORING'.
(Other definitions for adoring that I've seen before include "Loving, worshipping" , "Showing great affection" , "Passionate" , "Extravagantly indulgent" , "Worshipping; admiring" .)
