Re: Prayers and Thoughts request.
The last days can be quite difficult. I went through this with both my MIL and FIL (both were wonderful people, btw). MIL had ALS and FIL cancer. With that history, all I can tell you is that you have a lot of friends here praying for you and we are here if you need anything. Follow your heart and don't let anyone put pressure on you and yours to do more or less than you feel you need to do.
And probably the most important advise I can give is not to dwell on the symptoms you see know. Don't dwell on the disease. Use this time to remember and talk about all the good times ... those are the thoughts you want to keep forever. Make this time a celebration of Shirley's life, not a mournful waiting game for the end.
I pray for God's mercy, grace, and strength to help you through these difficult days.
