Sorry for your loss.
On the surface, the hope of an afterlife is comforting, and that is what pretty much every religion offers in one form or another.
The cruel part about being a jw is that at some point, every jw believed they were never going to die. They were going to be a part of the special generation that lived forever.
The reason it's cruel is because so many don't plan for anything, leaving themselves and, even more cruelly, their children unprepared and vulnerable.
Since the 1870s, there have been quite a few of these last generations of jw's, who are no longer with us.
