I can relate very well with what you are going through. I was my moms 24/7 caregiver for 3yrs prior to her passing in Dec 2008. She also suffered from Alzheimers. The further the progression into the disease, is the worst on the caregiver. When I had to put mom on hospice care at home, the pastor recommended the book called, "The 36hr Day". It really helped me understand the disease better and was able to help my mom. Also it helps if you can go to a counslor for support. Just remember, most importantly that whatever your mom does or says to you, that it is the disease making her do and say what she does, and please don't take it personally. I will say a prayer for you, and if no one thanks you, I will. Thank You for taking care of your mother. God Bless.
