Sounds like you and mom are perfect for each other..lol
If you aren't there when she cleans where are you? If you don't have a job or going to school,(I'm assuming) you should be there all the time..with all your free time your house should be spotless..If you have no income you owe it to your mom to clean whenever you can for room and board alone.
You can call the Health department and report the house but then you will get the joy of living in a shelter..
Only solution I can see is take the bull by the horns and clean it yourself. Without her help.
And sadly, the JW's forgot to tell the people of all the downsides of Home Schooling your kids... Too many are suffering because of it.
I have seen several climb out of their hole and gone for some state assisted schooling. They worked to get their GED's and went on to take college courses..the government helped pay for it too!
You can sit and groan about the situation or you can do something about it..
Best of luck in your decision..
Snoozy.
ps..Don't see it as one large area..just take baby steps and clean an area at a time. And buy a lot of strong trash bags..lol
