Question

Answer

'Exhausted by' is a little strange - it seems like a passive sentence (I was annoyed by that) but actually the housework didn't cause anything, so it's a little strange.

Answer

“Exhausted from...”means she recently did the housework and is tired now.  “Exhausted by...”means that she has been doing housework every day and is very tired of doing it.
