@jlam1950 you need an ombudsman or a person who would become your conservator when you’re unable to do so for yourself. Since you’re still dealing with the shock I suggest you find a Geriatric Assessment Center near you. They can help steer you with therapy as your illness progresses. And it sounds like you need to see a therapist now to help you with these feelings. There are 5 stages of grieving and anger is one of those stages. Since you’re alone you should if possible arrange for your continued care in a memory care unit when you can no longer function independently. I’m sorry for your difficult diagnosis.
