Good idea
It's probably also good to let yourself get over things a bit before you start on something like that. I imagine that you are probably currently simultaneously feeling loss and anger, so you can either run with it at the moment or wait until later, after the emotions have subsided a bit.

Actually, considering that, and as long as it's not a problem to you, I would say "Go ahead and paint now, while the emotion is strong, then look at it in a couple of weeks,"

That is not meant to be anywhere near as cold as it reads.
