Really sorry about all your troubles.
Sounds like things are getting sorted, for now, as you say.
I shop on Amazon & eBay, have Paypal acct. & Amazon credit card.
It is scary to think someone could hack into them & do a lot of damage!
We have Idenity Guard, you pay monthly for it.
Hope it's as good as they say it is.

Will keep your mother in my thoughts.
You're not alone on an aging, sick, confused mother.

Take care.
