I'm remembering the time when Gail was suffering in and out of the hospital, its not an easy job to see a spouse in difficulty.
He needs you now to be an advocate and guardian, from this fact you can call up strength that you didn't know you have.

I recently went thru a major combination of illnesses that I muddled through without realizing how serious the were. Now that I am better, I can see that I should have had more faith in the quality of the medical providers who helped me thru it all. I wasted a lot of energy worrying about insurance details that I didn't understand properly, and also medical details, because I did not have an advocate.

So, do your best in the areas of your abilities, get help from trusted friends, but understand that you are not in control of the situation, and call upon your personal higher power for wisdom and solace. (also use plenty of wine and music!)
Best of wishes for you both,
Jim
