Hi LadyJane, First of all I am very sorry to read that your husband has cancer of the liver, I should not even complain about my problems. Cancer is a terrible sentence to have.
I also wanted to say that I wish I could help with your question about the yellow in the eyes. I don't think necessarily that you have to be close to death to have yellow in the whites. But, maybe you could find the answers somewhere by doing a search if no one answers here. There must be some sites with information for you to look over. Good luck on your quest.
Shoot for the Moon
and if you miss
you will still land
among the STARS!!!
