Thank you all for your heartfelt replies - each touched me in a profound way with advice I've taken to heart.

Thankfully, Sunday was a "good day" - we talked and laughed during the 3 hour drive to Houston and he was "himself" again (it was one of those rare days when he wasn't feeling sick). It reassured me that there will be "bad days" with this but there will also be "good days", still.

Thank you for getting me through one of the darkest days I've faced so far -
