WOW thank you Lynnda, but your words were MUCH better. We left for a few days after Molly left us and went to Lake Tahoe at my daughter's time share and it was snowing and early one morning I was on the computer and happened to glance out the window to see a tri color beagle romping in the fresh snow off leash. We both about jumped out the window and we CHOOSE to think it was Molly saying she was OK. But that is just because we WANT to think that, not that we can PROVE she came back to assure us. As humans we LONG for a sign that there is an afterlife that we can see if only we "try" hard enough. I am not going to get into that here of course, but if there is nothing that you "see" or feel, that doesn't mean that it doesn't exist and that your baby is not fine and waiting for you.
The feeling that your loved one never existed is very common. I think it comes from the fact that YOUR world stopped but everyone else just goes on like nothing ever happened. We want to think the whole world mourns the one we loved and lost. I felt that way when my Dad died. The whole world stops and grieves when someone famous passes but for us "common people" we mourn alone. Please don't think that in any way diminishes your loss. YOUR world DID change, as it has for all of us, and here we understand because we feel the same way you do.
