Cathi,
My heart goes out to you and your family. My advice to you is to spend as much time with him as you can. If you can't leave your job then just be with him on the weekends. I spent the last two months of my Dad's life with him and wouldn't trade that time for anything in the world..(Well except to have him be healthy)
I can't even write anymore as I'm getting teary eyed.
My prayers are with you.
