thyroid, liver and possibly candida. does your gut swell up when you go outside in the cold?
get away from mercury and fluoride. i guarantee that is your problem. get lots of kelp for the iodine. you must eat less and eat only organic food. as soon as you can, hot baths with cold showers. hot sauna and then jump in frozen pond or snow. you must retrain your system and clean it up. the poisons are killing you by degrees(literally).
