Just a thought -- when you tried thyroxine before, it could be that the T3/T4 ratio in the formulation wasn't right for you. I've read that among the synthetics there are different meds with different ratios. There's some anecdotal evidence that PWMEs often to better with the natural forms which have a T3/T4 ratio of 20/80.
I'm pretty sure docs can check T3 and T4 separately and, presumably, prescribe a thyroid supplement whose balance is suited to your needs.
Am I right that you can't get decent herpesvirus testing in the UK?
FWIW, all my standard labs look normal to a GP. I went through 4 years of insisting there was something wrong and my GP becoming increasingly convinced I was a hypochondriac.
Even though my standard labs look normal, I have immune abnormalities and had 5 chronic infections -- HHV-6, EBV, C. pneumoniae, Coxsackie B, and Parvovirus B19. Our GPs are simply not prepared to recognize what's wrong with us.
I've long since given up even talking to my GP about my ME/CFS unless she asks about some treatment I'm getting. For the most part I just say, "My specialist is handling that." She's usually relieved that she doesn't have to deal with it.
