Wish I had words of wisdom and solace, but I don't.
I don't know how you as parents and grandparents live with the blinding pain of such startling and unimaginable loss - except that somehow you do - because regardless of the pain, you wake in the morning.
The heart beats, unbidden. The breath breathes, even in those times that hit literally like a knife in the gut, and you think that you just can not bear it. Those times when the imagination runs wild, then you realize you have to reel it in.
For what it is worth, remember this. It is true regardless of spiritual belief or the lack there of. Kaelan is free from all suffering. Whether he is in a "better place", or dwells now only in your hearts, he is OK. Free of pain. Free of suffering.
Remember that.
Remember that he abides always in your hearts and memories. Remember that he lives on in every life that he touched, in every memory that anyone has of him. We are as shaped and influenced by the young as much as by the old. If in no other way, each of us is immortal in that the effect of our lives on others does indeed ripple out in wider and wider circles, and down through generations.
I don't know you, Sandy and Caroline. I only know who you are, and doubt seriously that you recall me from our brief introductions at a Getaway. Regardless, the simple act of reading this thread, contemplating your loss, reading the posts of those who do know you, your family, and Kaelan, changes and influences me, as it does everyone who reads here. Kaelan lives on, even in someone like me, who never knew him at all.
Nothing that I write here can touch your pain and loss, but in the event it brings some measure of comfort in the midst of your terrible pain in the time ahead, I wanted to share these thoughts.
