I had long vax syndrome from 2022-2024. POTS, dysautonomia, couldn't sleep, rashes, Reynauds, problems regulating ambient temperature, blood pressure regulation problems, etc, couldn't be in sun, orthostatic hypotension, etc. I was on the couch for months. I decided to do as much physical exercise as possible and consume superfoods like clams 2xs a week, blueberries, kale, walnuts, etc, daily. At first I could barely do any exercise, then it got slowly better. I was sure I would never recover. I read somewhere that if there is nerve damage, it can take 2-5 years for nerves to grow back. Not sure if that is true, but I definitely turned a corner for the better at the two year mark and feel pretty much normal now. I found the best way for me mentally when I was sick was to accept my current reality, but realize that I could still try to improve on it. Good luck, praying for you!
