Hi Sam,
I have been where you are (very long story and very similar to yours)and finally completely desperate.
I had been on curezone for several years (after exhausting all of modern medicine) and done most of the cleanses, the zappering, the supplements and followed the diets, (I still eat a great diet and take one supplement: cod liver oil, just because I craved it). Spent literaly thousands of dollars on trying to get better.
But my health turned around when I went to a classical homeopathic practioner. You can see more at www.abchomeopathy.com but I would suggest seeing one in person because they pick up on things that you would not think to write about. I still don't understand why it works, I just know that I feel better than I have in years.
Also, if you believe in God, pray.
My Best Wishes to you!!
Deb
