I can commiserate with you on your long list of symptoms & lack of easy resolution toward diagnosis! Pretty much what I came in with last June--except I arrived with a pot load of scared too. Can't point in any direction whatever but will say that someone from the Community Welcome team will be along & may suggest forums for you to re-post at where your posting will get more "oh, yes!" responses.
This is a terrific place for gathering solid information & for acquiring solid friendship & support--the kind that gets you thru the dark hours when you don't have answers but still have questions, when you want to just

at someone but your old friends are sick of hearing it, when you want to

without being told to cheer up, things could be worse.
This is a good place to be & I'm glad you're here, Phil. I can't diagnose a goldurn thing, but I can listen, listen, not tell you how to feel, and listen. Knock on my Profile Page any ol' time if you want to visit.
Hope you get
the answers soon.
