Sounds like lyme and or coinfections plus heavy metals which often go together. You are putting too much faith in the testing (which has yielded false negatives) and using the wrong doctors. ND's at this point are almost worse than MD's - unless you can find that one in a million.
Was the thallium test a stool test, urine, or hair? If you did/do have thallium it can explain why you are suffering so much. It's in between mercury and ionnizing radiation in terms of severity. Iow one of the few things worse than mercury.
All of the detoxing methods you did will not do shit if you have babesia or lyme, and coupled with possible heavy metal poisoning it's likely that you just made things worse and worse - not your fault - it was the fault of your doctors who don't understand the problem.
I would stop everything, all supplements, all treatments, all special diets, until you can get some new bearings.
Definitely get a hair mineral test - doctor's data is probably best.
Try some cranberry extract for the urinary infection.
If you're strong enough start on saunas.
It's a long and complicated case, I might write more later. But it's going to take many tens of hours for someone to help you.
