Wow, what a clear well thought out informed post. I envy you. I never was this cognizant in my early days of illness.
My take; you're infested with parasites, for sure in your liver and probably most of your glands, which will provide all those nicely articulated symptoms. And doing just a herbal cleanse won't even touch any of those places.
So my advice? Dr. Clark's protocol WITH zapper. It's the only way to get the little buggers outside the digestive tract, of which you clearly have many. Do that, and see what's left after a week or two.
Come back, with another very lovely such 'report', and we'll deal with the other things then. Toxins, probably. Or, just download her book 'Cure for all diseases' here for free, and read it yourself for some of the best correct answers available.
