With all that is going on with you, it seems to be mainly an infection in the body somewhere. I had many symptoms that you describe, all the tests, yet they couldn’t find anything! After reading some research in NIH, I asked for a dosage of amoxicillin which the doctor would not do until the 4th visit. I went through my patient portal 4 days later to let him know that my sickness had gone away! They found later that I had one of the worst infections that was hidden by my gallbladder! It’s been a year now and no symptoms of the condition for which I had gone to the doctor to be treated.
