Jamie...
I couldn't help but cry when I read your post because I am in the same boat as you, sort of. I understand your frustration with the brain saying "Let's go do some simple task" and your body saying "Oh no, I don't think so!" I struggle with COPD, RA, Congestive Heart Failure and various other mild complications and I can so relate.
I get so frustrated over the simplest of things like taking the cap off of a bottle, (while I am dying of thirst) getting pills into my mouth without dropping them on the floor, (and picking them back up before the cats eat them) preparing simple microwave meals, even just walking to the bathroom is taxing lately.
Pick your battles, hun. If you need to rest before you put another liner in the trash can; so be it. At least we aren't completely bedridden and totally helpless. I know how badly you feel about not being able to do the things you used to do easily; but it always helps me to realize that I could always be worse off.
I do pray for you, my friend, and also for myself that we might find an easier way to do things, that we have the patience to rest in between chores and that we realize that we are blessed to have so many friends we can turn to when all we want to do is crawl under the blankets and cry. Each day we wake up is a victory! (Even if we don't accomplish a single thing.)
Hugs
