@maison rustique, My sincerest condolences.
I know exactly how you feel because that’s how I felt when they called to tell me my mother had died (in Jan. 2001). She had progressive supranuclear palsy. I was her major caretaker, and her final days were awful for her. I was glad that she was no longer suffering (she had actually signaled that she was ready to go) and felt huge relief for myself.
