Before the heartbreak at the convalescence place (4,6)

'before the heartbreak at the convalescence' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'place' is the wordplay.
I cannot quite understand how this works, but
'place' could be 'rest' (resting is a kind of placing) and 'rest' is found in the answer.
The remaining letters 'centre' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
