I should be relieved but I'm pissed. No closer to figuring out what the real problem is, but it's enough of a recovery that I can't argue when they tell me they'd rather I not come down yet. I feel powerless and pissed off and still worried that something mysterious is killing my dad while different groups of doctors take turns filing the same tests.
I feel the same way: Scared/worried, angry that they can't figure this shit out (years of science and we still get no answers...argh), frustrated, vulnerable, powerless, majorly depressed (which makes me withdraw when I shouldn't), all of it. I feel for you so much and for your family. Stay strong and hang in there, trite as that might sound.
The cyclical nature of what your dad's going through sounds all too familiar, too. I'm just so very sorry...
