Oh Mp,
I am truly sorry that your Mom is being this way. Apparently, the disease has a hold of her and she can't control it.
This is not fair to you. She needs to think about your needs instead of her own.
Is there anyone close you can talk to about this that will understand? You are making yourself sick from worry.
Please don't blame yourself over this as this is your Mom's choice. I doubt there is anything you could do or say to change her.
Sending you lots of hugs and hope things will look up for you soon.
