S.P.
L., I hope you are making time to pamper yourself, because you have it rough right now, and you need to care for the caregiver - YOU!
My grandmother also suffered Alzheimers. I'll never forget one of the last times she "surfaced" from wherever the disease carried her mind away to, and realized how bad things were. She begged us not to come see her like this. How painful that she had to realize her own state and feel humiliated.
Here is what I did. I wrote down all the wonderful things I could remember about her. I was the oldest grandchild and had the blessing of having her in my life the longest. There were so many wonderful times we shared, and memories of things she did for and with me. I was able to think of my "mama" that way, instead of the way she was for the last few years of her life.
You and your family are in my prayers...
