I have to start a second answer because the quote box wouldn't let me escape.
As CovertsadJW said, only do what you can.
My mother doesn't really fully appreciate what we are doing. As a JW, she would be shunning us right now if it weren't for the fact she's been living in a rat infested hoarder house and her "spiritual" children wouldn't even set foot in it. So even tho I know this, they are still people that need help. My father isn't a JW and is in the worse shape after having a fall. So cleaning the interior has been ramped up so that he can come home hopefully. This has taken up alot of our free time and involved cleaning really nasty stuff.
We are at the point tho, that some outside help is going to be looked at.
There are others here that have had the same experience. Hope that you can find a solution.
