I just re-read my previous post. I hope I didn't sound cavalier. I can only imagine what you are going through. It must literally be like the loss of one half of yourself.

I just hoped that some of the wonderful memories you have made and continue to make might be a comfort to you.
John must be strengthened every day by your love and the way you care for him and Nathan. When he recovers, John will be comforted by the memories of that loving care. And those same memories can bring comfort to you.

Please know that you are always surrounded by prayer.
