Hi,
Welcome to our community BlackCat. I am glad you found us. You will find this is a supportive, caring group of people who understand.
It’s good you see the mental changes in your mom as part of her illness - but it still must be hard. Have you had a chance to talk with the doctor or nurse who are caring for her? Does someone from the healthcare team visit her at home?
I understand you want to care for your mom at home and I can understand why she might not want other people in her home. But do you think you can safely do this alone for much longer? It sounds like you would need superhuman strength - both physical and emotional - to care for your mother and her needs as well as your own health needs and the dogs + all the everyday things in life. Caring for yourself was written by the healthcare team of the Canadian Virtual Hospice. You might find it helpful.
Do you have friends BlackCat who support you? Is there any way other members of the family might be able to support your mom and you?
Katherine
