Suffer again without European help (7)
I believe the answer is:
relieve
'help' is the definition.
(I've seen this before)
'suffer again without european' is the wordplay.
'suffer again' becomes 'relive' (live through something again).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'european' becomes 'e' (abbreviation e.g. EU).
'relive' enclosing 'e' is 'RELIEVE'.
(Other definitions for relieve that I've seen before include "Take over (from) - ease worries (of)" , "Soothe" , "Alleviate, assuage" , "Free someone from duty by taking his place" , "Free from obligation" .)
