I think I know exactly the kind of fatigue you're talking about. When Lupus and/or my fibro flare up, I will hit a point where I say "I just hit the wall" because that's exactly what it feels like to me. For me, sometimes it's there when I wake up and I know it's going to be a pointless day; other times, I can make it to 10pm. It ain't fun, that's for sure. My grandson will come to me and tell me he doesn't have any spoons left. Which, for those unfamiliar with chronic pain or autoimmune fatigue means you only have "x" number of spoons to use during the day, and when the last one is used you "hit that fatigue wall" where even walking 12 feet to the bedroom feels like a mountain to climb.
I knew I was stressing about the election, which tripped off flares for me... but it also hit my grandson, too. I don't think either of us truly realized just how stressed we'd been. Took me until Thursday before I could even climb out of bed and think about looking at DU (and nothing else). I'm still not great... but I'm beginning to come out of it while trying to make plans or steps for when things get really bad. DU has been really terrific for prepper-type info today. I'd already planned to lay in extra canned goods and shelf-stable foods, but picked up a few more hints while reading today. As long as they don't cut SS off completely and immediately, I think we'll be okay. If they do, well... there's going to be a lot of us old people out on the streets, picketing and protesting with canes and wheelchairs, I guess. I'm trying not to dwell on that aspect of what could come to pass, tho.
Just be gentle with yourself and give yourself permission to let chores go by the wayside for a while. If your body wants to lay down and escape the madness for a while, let it and enjoy the peace of (hopefully) good dreams. We're all in this together, remember!
