I feel so bad for you. You seem like you've tried everything and you still feel so sick.
Can I make a suggestion that is a little outside the box? Have you ever considered you have too much brain fluid pressure?
Basically, there is a condition where the fluid inside the cranium squeezes the brain, causing headaches, visual disturbances, neck pains in the cervical area and shoulders, and other symptoms. Sometimes people will have chronically clogged ears or sometimes clear liquid running out of the nose. People have it from birth, but it only manifests itself after puberty (or thereabouts)

You might ask "why would a person have too much brain fluid pressure?" The reason is that many people have mal-formed or narrowed ducts carrying around the cerebral spinal fluid. So the fluid gets trapped in the cranium. This might be related to genetically weak or floppy tissue structures (I don't know if you or anybody in your family has hypermobile joints or stretchy tissues). The ducts don't stay open because they are flimsy, weak.
And many times the high pressure in the cranium will squash the pituitary gland completely flat. In all you tests, has anybody ever examined the shape of your pituitary? The condition is called Empty Sella Syndrome, because the pituitary capsule looks empty.
I only make this suggestion because idiopathic intracranial hypertension (IIH) is not unusual or strange at all. In fact, Cort, the former owner of this website himself had it, and the doctor told him he had IIH also. He wrote that he had a lumbar puncture and actually felt better for a few days after.
http://phoenixrising.me/archives/2127 He wrote a feature article about it in 2011, and many patients posted that they had it. It seems to be co-morbid quite frequently with ME/CFS.
IIH and Empty Sella Syndrome is actually becoming more common, and it is especially common among young girls, many of whom are obese. I believe the obesity comes as a result of the screwed up HPA axis and hormones, and not the body fat squishing the brain fluid (as some numbskull docs are saying).
But the important thing is that your brain is under unusually high pressure, and this can cause all kinds of immunological and neurological reactions in the body. They might be causing the anxiety, insomnia, dysautomonia that you have. It also opens the doors for all kinds of CFS-related disorders; and interstitial cystitis is definintely on that list.
The best part about high brain fluid pressure as a diagnosis is that you simply have to get your doc to give you prescription for Diamox, a very common diuretic. It is prescribed for glaucoma patients, because they have too much pressure in their eyeballs, and the Diamox dries out some of the over-pressure.
Diamox only becomes a problem if you take it long term, then I think it causes Potassium depletion. Otherwise it is dirt cheap, and completely safe. Like any drug, as a CFS patient you might want to start with a very low dose and see what happens. If it does not work or doesn't agree with you haven't spent thousands of dollars.
BTW people who have IIH have terrible reactions to Florinef and stimulants. Stimulants and more fluid pressure are exactly what IIH patients do not need. I had a horrible reaction from Florinef. I suspect many of us have screwed adrenals, possibly from IIH in the brain.
The studies in Pubmed tend to focus on the prevalence of IIH in obese women. But anybody can get it, and it is probably associated with ME/CFS like symptoms.
