'substitute' is the definition.
(thesaurus)

'always upset about the general situation' is the wordplay.
'always' becomes 'ever' (synonyms).
'upset' is a reversal indicator.
'about' is an insertion indicator.
'the general situation' becomes 'lie' (I've seen this before. I am not sure about the 'general' bit.).
'ever' reversed gives 'reve'.
'reve' placed around 'lie' is 'RELIEVE'.
