Hello atanyrate: This appears to be your first post here on PC. So... welcome to PsychCentral… from the Skeezyks!

May the time you spend here be of benefit.

By the way, I'm 68... almost your mom's age.
I see you're in Canada. So I don't know what types of in-home services are available where you live. But if there are some you can access, the most straight-forward solution here may be to avail your mother (& yourself) of some in-home services so you're not stuck dealing with all of this 24/7. Your mother's not likely to change. And it's probably going to be tough to put up with her behavior day-after-day for who knows how long. I wish you well...
