Zdog, you wouldn't be the first person seeking a diagnosis to be told "it's all in your head" and you probably won't be the last. You are in very good company with many of our fellow KAers. Just don't give up until your questions about how you are feeling are answered satisfactorily and you are given treatment to help what ails you.
As for the uncertain test result - ????
I've never heard of that. That's just whacky. Most definitely get another done.
Good luck with it.
Hugs,
