How do I stay positive? I feel like my body is letting me down.

I get that for sure. I have been on my own chronic illness journey for decades now and I still haven't figured out how to do that exaclty other than distraction, distraction, disctraction. I am the busiest disabled person in the world, I think! Writing stuff, video games, got a dog, etc. etc. It is what works for me when what I call "the blahs" hit! Just know, though, no matter what, you are not alone, if that helps! Keep on keepin' on, DPM
