I am sorry to hear that about your dad. I watched as my dad had to struggle more and more to hunt until he just finally had to give it up. It is hard to see strong people go backwards and the best we can do is help until the helping is over our head. You should call the office of aging in your county and check into the visiting nurse program to help take some of the load off you and your mother. Medicare/medicaid should take care of that. Talk to him about the good times you had hunting with him and help him reminisce, it will help you too.
