Gentle hugs are on the way, @kamama94.
You are going to be busy next week as you get set for and begin dialysis. I bet you will feel better after you get used to the 'idea' of having dialysis. I did not have any prep, as my kidney failure was sudden, although in hindsight I wonder how much of my misery with failing liver was enhanced by a failing kidney. Guess I'll never know.
When I was reading your earlier post, I was thinking that your neph is a gem! Did he tell you what he meant by feeling worse?
