I'm pretty sure you've already looked into this but I couldn't scroll past without dropping in my thoughts; feel free to ignore them. I'm dealing with similar problems as a post-covid sequelae, in my early 20s with debilitating problems and also having to get to the root cause myself as doctors are clueless. Have you had your gut microbiome tested (with zonulin + IgA + parasites, fungi and viruses)? If so, feel free to plug it into cfsremission.com to see if something pops out. Oral microbiome and health? SIBO test? Candida? Immunological check up? ANA? EBV or other latent viruses reactivation? Elimination diet / carnivore? You could also try FMT if all else fails (either expensive at a clinic or DIY at home). Good luck man, you're stronger than most of us.

I do want one actually, yeah. Much of my decline started after heavy antibiotics a few years back, and I've experienced temporary relief of some symptoms from antibiotics last year, but then they came back with a vengeance.

I'll be seeing a gasteologist who has published papers on FMT (most here haven't even heard of it), and if that fails, I'd definitely like to DIY.
