Hi Drubear - thanks so much for your conversation(s), here in the community. Clearly, you are managing quite a bit, based on the conditions you've shared here with the rest of us.
I see my site-friend, , has suggested how you can search for the many articles published here on our COPD.net platform. For your convenience, here is a link to many of those articles: https://copd.net/search?s=end%20stage.
When you have an opportunity to look them over, I am sure you will find them to be helpful, in a practical way and, interesting, too, as whirledpeas suggested!
Wishing you well,
Leon (site moderator COPD.net)
