Dear Scared Husband,
Gosh, I don't know what to say to make you feel better. They say that God only gives us what we can handle, but I don't believe it. You have every right to be angry. My only advice to you, its to take your energy and focus it on making your wife's life comfortable, peaceful and special. Unfortunately, we know that this cancer is viscious and unrelenting. We cannot change the reality of what is going on or what is happening to our families. All we can do is make our loved ones feel better, as hard as that may be.
I am going through the same thing with my dad, who is my best friend. I feel that whatever I can do to make him feel comfortable is the only gift I can give him right now.
Also, if family and friends are offering help, take it. You need to give yourself special treatment, too, even if it's a walk outside to relieve some stress.
I wish I could do more for you or give you more advice. Hang in there...
