Bob,
I can't express how sorry I am.

Last Summer we had a family event I didn't post about. My 12 year old grandson suffered severe brain damage from a clump of arteries in his brain that ruptured. After brain surgery he then suffered a stroke. He was in very severe shape. We didn't expect him to live. Four surgeries later, he is home and walking. He has a long way to go, but it can happen. The youth of your son is in his favor. Take care of yourself.
Thinking of you,
Billye
