This was very hard to post here. I lost my Dad 1.5 years ago and it is still so hard. All you can do is pray, talk with the doctors, pray, and go on living.
It's a blessing to have a good doctor you can trust! If need be, talk to him alone and see if there is anything you can do. Write down what he tells you. Listen closely, what you don't understand ask to be explained. Knowledge is power. Well meaning friends and family can help or hurt the situation. It's best to be able to explain exactly whats going on to those who need to know. Trying times like this tempers can flare and feelings easily hurt. Forgive and forget. Be supportive, but take some helping hands too! Remember you have to be strong for him and that means taking care of yourself too! A quick trip to the barn saved me more times than I can count. If you need to talk, pm me and I'll give you my phone #.
Believe me, been there.
