I am slowly but surely taking over more and more of the daily tasks of living for my 88 yr. old mother who suffers from degenerative spine disease, and macular degeneration. She still maintains her own personal care, but I do most of the cleaning, cooking, pet care, all transportation, and will soon take over paying the bills as she is losing her sight. She often says "I am useless, I take up all of your time." I assure her she is not, and that I value her friendship and companionship, and I have time as I am retired, have only a cat at home to take care of. Her mind is sharp as a tack, in fact her memory is better than mine and I am only 63, but her body is failing on her. Has anyone had similar experience and how did you handle it?
