I can't see many of the things you listed causing kidney problems and hypothyroid. It had to be something you were eating in conjunction. And the reason you were probably feeling worse and worse was because your body wasn't eliminating the toxic load from the candida die-off. In order for your body to do this correctly your liver and gallbladder need to be functioning properly which you can assist by taking milk thistle and dandelion. Also, you need to take a fiber supplement like psyllium husk, or aloe vera to speed transit time and help keep good bacteria flourishing. There are many factors here as to why you ended up feeling "worse and worse". Another thing, is that Colloidal Silver (although touted as healthy) is actually poisonous to the body (do your own research on this and you'll agree). Maybe that's why you ended up with kidney problems. As for hypothyroid problems, that's most likely related to diet. Were you consuming a lot of soy or containing products? This could be a contributing factor.
