Tre, I am constantly appalled that here in the United States we can get enough care (just enough, in most cases) to stay alive but never enough to see, hear or eat. That vision, dental, and audio are not covered by most insurance polices or by Medicare is deplorable. Add that those three can be so expensive and it's unconceivable that they aren't covered.
I'm not sure if there is hope for you condition to be reversed or its progress to be slowed, Tre, so I will wish you the best outcome possible and give you my sincerest concern and the warmest hug I can send over WiFi {hug from me to you}
