Like "I am very sorry for this decline in your mother's health and for the sorrow you feel. I pray for the best for her and for you to be comforted. I am so glad that you had a good visit with her. No doubt she was very blessed by it and is relaxed, knowing that you love her and that you are going to be OK without her if she doesn't recover from this. Of course you aren't prepared for the emotions you are feeling. Facing the loss of someone we love is never easy. Pray for God's will in her life and for what is best for her and cherish all of your happy memories. That's really all you can do. Love to you, Sue."
