I'm sorry to hear your best friend is doing poorly. We lost what I always called Daddy's baby girl (Dinky) a couple years back after 16 yrs of sharing our lives together and it is tough when you must face this moment. I cried a lot after having lost her but, I also knew I had to be unselfish for her an allow her to pass peacefully with the ones she loved and trusted around her. I don't envy you as I know how it hurts but, truth is your buddy never needed you more in life than he does now.
