Sounds like Candida is the root of your problems, especially after being on Antibiotics for that long! Keep on doing the diet and taking the probiotics. You may want to try threelac, it has been helping me. Do some colonics possibly and cleanses are a good start. Research Candida and go to that forum. When you have Candida it can make your thyroid go all weird, as well as liver and adrenals. I tried taking the meds for my thyroid and felt better for a while but then felt worse. The thyroid was not the root of my problem, the Candida was making me hypothyroid and once you get your candida under control, the other organs will be able to balance themselves out.
