I am sorry you are having all these problems. I have had some of the same symptoms too.
I am in central NJ (shore area). You too?
I second what uppity said about lyme. I was dx with MS for 7 years before I found out I had lyme. The usual labs (labcorp, Quest) use cheap test kits and their tests for lyme are highly inaccurate. Lyme is a tricky bacteria because the bacteria can evade the immune system and your body does not produce antibodies. No test is 100%, but the best lab in the country for tickborne diseases is Igenex in Palo Alto, CA. Any Dr can sign the needed form. Lyme is a clinical dx and a negative test result doesn't mean you don't have it.
BTW shortness of breath is the classic symptom (there are others too) for Babesia, which is another tickborne co-infection. 60% of people with lyme have 1 or more co-infections. I had Babesia also.
Good luck on your search for answers and hope you feel better soon.
