Sorry to hear this my friend! My prayers are sent to you and your family. My dad was in a coma, but woke up yesterday. At 79 years old, he is down to 130 pounds. He is a life-long smoker and kind of gave up his desire to live recently (his nursing home tried to make him quit so he went on a hunger strike).
I think I am as stubborn as he is, so his curse is that I'll probably follow his footsteps.
Again, sorry to hear about your loss. Hang in there!
