Yup, and Marty, [and Vince, in advance] that's all I'm going to say about it -- your numbers went down. Now, when else other than clinic are you going to choose to breathe like that?
Where you are, is way more important. If you are on BiPAP, as comfy as can be, getting out when you can, with whoever you want to be with, managing mucus, getting nutrition/calories and deep sleep, those numbers don't mean a thing.
If you aren't, focus on those things -- the variables that frame the quality of your remaining life, however long.
My husband was about where you are three years before he died, three years that he lived to his fullest [I did not say, your fullest or my fullest, but his]. Just plan to do the same for whatever there is.
I balanced all, brought all to mind,
The years to come seemed waste of breath,
A waste of breath the years behind
In balance with this life, this death.
--W.B. Yeats
