So sorry for the loss of your mom. I just lost mine a week ago and am going through the same scenario you described. I'm at peace with the passing but as you say, there is a dread about the days ahead. A whole boat load of feelings are happening because of all the current JW contact and the coming memorial this Saturday.
"We are sooooo close Dag!!! We are almost there!" was part of an email I received yesterday. Makes me sad, the delusion of it all.
I wish you strength for the days ahead and comfort during this diffcult time.
