@Willow I think I should add to this that it isn't just, "Yay, I can lug more bags at a time."
At least once a week I'm struck with this profound gratitude over what my body is able to do now. I'm afraid to use metaphors because I don't want to be offensive, but it was like having been cured of a chronic wasting illness. Pre-T, I didn't judge myself for being weak or anything -- I didn't really know I felt weak, only that exertion hurt emotionally as well as physically. Because I'd hit my limit before I thought it was there, and so I would hit it hard, every time. That hurts! And is taxing and triggered despair.
And I didn't understand any of this. It was before I'd even heard of spoons theory, so I'd just be sitting there, devoid of spoons, wanting to cry, and with a job "unfinished."
I still feel the ghost of those old limit-warnings when I'm doing things now, and that's what triggers the gratitude, I think. I'll look down and realize I was just able to move a 70-pound tub of books, and some thing I wanted to accomplish is finished. I might be breathing heavy but I'm standing up and feeling good about myself, that nice dopamine thing. And I'll want to cry a bit, for different reasons.
