Yes, well, try your best not to get too stressed out about it, and just work within your capabilities, since we know that we pay when we over-do it.
I think I can say that I did indeed get over "Long Covid", which manifested in really very much the same manner for me several decades ago as Chronic Fatigue Syndrome. It lifted away "magically" on its own after about two years.
Similar to LC, it started out after what seemed like an ordinary flu, which was pretty typical back then.
I'm trying to be patient with myself this time around (about a year after first succumbing to acute Covid), and think I'm gaining some ground by just using prescribed stimulants to counteract the fatigue, which, thankfully, is really my only symptom.
But I think being "Buddhisty" is a great approach!
