Hi Freedom, and welcome in here!
Have you got into a pacing routine yet, got your triggers and your sweet spots sorted?
Despite having all this sorted out pretty well, fibro put my energy down to 40% and now jab-triggered MCAS to 10-20%.
So shopping has to be 5' there, 5' back and 20' in there.
My sleep's got a bit out of control again, Saturday night I was up 3h, then slept another 4.
Yesterday I didn't think of anything to do after less than 8 hours, which was by far not enough.
So today at 6 I took a hot water bottle and put on a 1h Yoga Nidra recording, which repeated more than 3x before I felt comfy to get up - today that was a really good idea. Hasn't increased energy much, but at least it was sort of "restored".
Having a cold on top of that must be gruelling. Due to self-care and masks I haven't had one for >2y. At least regarding the cold we can for once say: "Get well soon":
