My suggestion is to prove you have a problem and then you can get treatment. Check out the candia5 test, its pretty cheap. Additionally I would consider getting checked out for diabetes because this is often associated with constant thirst. Another problem is that you likely have a histamine intolerance issue which can be reversed with both natural and medicinal drugs…this is what can cause the anxiety and panic attacks. To me it sounds like you have a histamine problem that has been left unchecked and has caused a variety of other health problems.
If you can travel to spain, I would consult with Dr. Prada Pascual.
