Hi Lori, i'm so sorry to hear of the struggle you are in, how very painful indeed.

I can think of only one other avenue of investigation for you to follow as far as diagnosis and treatment are concerned, and that is environmental toxicity. There are cases I have heard of which produce symptoms profoundly resembling various mental illnesses. We are exposed to so many substances that some of us reach a point of extraordinary intolerance requiring a modification of environment to exclude paints, carpets, pesticides etc. It must sound like a long shot, but then again, you've passed all the appropriate tests to determine brain function etc. Environmental toxicity while still a relatively new health issue has been around long enough that there are even entire communities set up to accomodate those afflicted.

As for David, well, I hope he can get a grip. I know from experience that our loved ones are also culturally programmed to have an aversion to anything resembling mental illness. It can be a real challenge to bring them around to facing it squarely like they would if you had a bad case of the flu. It sounds like he's pretty spooked, but is behaving badly as a result.

There are some folks here who are very good at internet research. Sadly, I do not number myself among them. However, if you need help finding more information on environmental toxicity, post a request for research assistance in General, and you'll be pleasantly surprised at how much information comes your way. Take care Lori, and do please keep in touch. You don't have to go it alone at least.
