You have my prayers and my sympathy. My uncle went through something similar. As his mother's (my grandmother) health declined, she lived with him in his house for about the last 7 years of her life, and she died in her bed in his house about two years ago, so it was especially rough for him because he took care of her and grew so close to her in that time. I know God will be with you and I'll pray for healing and comfort for your grandparents.
