mortality is not a bad thing. It makes you appreciate the life you have. I know that many JWs ignore health issues and are constantly postponing things because they can do it in paradise. As a result they live in a small way unfulfilled lives.
Embrace this life and seek opportunities to make it everything you want it to be. Make this life a valuable one. who knows what there is in the infinite future. There are a finite number of atoms in the world and who knows what you once were or what you may become in future.
