Recover or collapse, finally, after period of relaxation (7)

I believe the answer is:

restore

I'm a little stuck... Click here to teach me more about this clue!

'recover' is the definition.
(thesaurus)

'or collapse finally after period of relaxation' is the wordplay.
'finally' suggests the final letters.
'after' is a charade indicator (letters next to each other).
'period of relaxation' becomes 'rest' (I can't justify this - if you can you should believe this answer much more).
The last letter of 'collapse' is 'e'.
'or'+'e'='ore'
'ore' put after 'rest' is 'RESTORE'.

Can you help me to learn more?
