Shit you’ve been through a lot.
Look into heavy metals. If you have any amalgam fillings get them out. I’ve heard from several people that they could not recover from candida without chelating them out first. Vaccines in the 90’s also contained thimosermal.
I know I had a fairly high TSH when I crashed in november. Now it’s normal. But I would say that theres a possibility that your thyroid will recover on its own after you get through all this shit.
First get your metal fillings out if you have any. Then get some DMPS or ALA. I really don’t recommend DMSA when dealing with bad yeast unless you have to.
