Coleen, so sorry to hear what you, your mother and family are going through. You are so right to call this a "wretched" disease, it causes so much suffering for so many. Try to find comfort knowing that many will be sending thoughts and prayers your families way. Although it will be difficult, try to value the time you have remaining with your mother. I am sure in the future you will cherish these memories however painful they may be now.

God bless you and your family.
