You posted pictures a while back of very distinct roundworms. They are not easy to get rid of, so it's very likely you still have them. They could be causing the majority of your symptoms, and also the reason why treating candida and your other health issues isn't working.
I have many of your symptoms, and they all totally disapear when I get clear of the parasites. If that is the reason for many of your problems, all the diets and supplements wont be able to work properly for you until you are clear of them.
I really think if you would concentrate on the one issue that you are positive you have, you might find yourself in better health, and in a better place to tackle the rest.
That is my suggestion. The problem is finding what works for you, as it appears to be a very individual thing.
