Matt,
I will be praying for your wife. It is so difficult to watch someone that you love go through the suffering. There is sometimes a feeling of guilt that you can't "fix it". I pray that you have a strong group of family and friends that are supporting you and your wife. Encourage her to take a little time for herself once in a while, preferably with a friend and not alone.
And I will and am praying for you. The questions,concerns, dreams, and fears that invade our thoughts during these times of trial can be ovewhelming.
I have learned and am still learning to be quiet. To listen for that "still, small voice" that has been comforting those that are suffering for a long time.
I pray that the transplant is a success and that your relationship with your wife and the Lord will grow a hundred fold....John
