Bonnie,
When we are in the depths of crisis, it seems like there is nothing we can do. All our wishes for health and strength for our loved one have come to naught, and we feel helpless: we have done all that is humanly possible. And yet, that is a great deal. Your love and steadfast care for John has been a gift beyond measure to him, and is a blessing to you both even - and especially - at this darkest of times.
