See a doctor: Some questions here are easy to answer. In your situation there are too many possible things going on for anyone here to provide meaningful advice other than your symptoms warrant careful evaluation by a good (ideally holistic) doc. You might have an infection like lyme disease/babesiosis, a neurological disorder, food allergies, heavy metal or other poisoning, B12 deficiency, anxiety disorder etc.
