Bob, I have had that thick goo for 6 years now and it even chokes me when I sleep which shuts off breathing. It has been the hardest thing to manage, by far. I hack blood, sometimes by the mouthful, and have for 6 years. It worried me long ago but it's just life now.
My wife walked away from "the patient" about 5 years ago, but started withdrawing as soon as she heard the words, "No treatment, not reversable, no cure." I try to empathize but it is tough at times. Hopefully, this will be behind you soon. From our eyes, the world didn't really change. Seeing the angst and tears from those I know is a constant reminder that I have radically changed in appearance.
Hang in there, it may take some more time.
Best wishes always.
