If it helps at all, something that always got me through stuff like this was what my grandfather told me before he passed away.
One day, a man's wife died. After all others had come to pay their respects, one of his best friends came by to do the same. Yet, as he walked in the door, he found the man singing and pounding on a drum! "Your wife is dead, and I understand your pain..." the friend said. "But don't you think drunkenly singing happy tunes and pounding on a drum is taking this a bit far?" The man replied, "In the beginning, my wife had no soul. With one change, she had a soul. With another, she had a body. And with a third, she has a body no more. So just as the four seasons are in perpetual change, so is she. And so are you and I, my friend." And so the man concluded, "Just like the four seasons, the cycle will begin anew, and we will be reunited once again."
I know its quite paradoxical. It took me a while to really grasp the whole thing, probably because I was 6 when I was told this story. But it always helps. even if its only a little bit.
