Im sorry to hear bout ur mom. My father had cancer and went thru the same thing. I would suggest looking into hospice. They are truely a blessing to have. They can help a lot.
We had 2 nurses during my fathers cancer. They helped my mom alot. They even were kind enough to help cook and clean a bit. And they are 24 hrs so u can call them anytime. For questions, emergencies, and general help. They even checked up on her after he past. They helped ease alot of the stress for her and me.
Your family is in my thoughts
Doesn't sound good. I would get her affairs in order.
Someone should definitely be there for her at all times.
Are you taking care of her or are there others helping? Hospice?
Other family should be notified about her condition if not done already.
