Welcome Donna.  Deeply sorry for your losses.  I can't imagine the isolation that you feel about being your mother's caretaker for eight years.  I have a sister in law that gave up her life - moved across the country to take care of her brother until he passed from a brain tumor.  Now, she is her mother and father's care taker.  She has no real life of her own - especially since the pandemic and she is isolated with her parents most of the time.  Take Care and Be Safe.
