There are MANY of us out here who understand exactly what you're talking about. It's a life-changing condition, and no one has the answers for a cure. It's not just long-COVID. It's a long haul from other viruses, too, which means it's been around for decades - maybe centuries. Where is the research and help? I have been living this way for 2 years, and my suggestions are to eat as healthy as possible, do what you can to improve your sleep (this has been a real challenge for me, and I have resorted to medication, which I didn't want to do), and try to avoid stress at all costs. I still have many bad days and bad weeks, but I think my good days have increased and I'm going to keep trying, no matter what. That's all you can do until the medical community comes up with some answers.
