I think that, until you have some genetic analysis done, you will never learn the nature of your physical, mental and spiritual reality. Sure, it will probably cost some money. In America, that is now $500-$600 for a complete workup and a lifetime of access to developing knowledge in the medical field. Sounds inexpensive to me. You have Hashimoto's and some others which lead you onto the genetic suspicion path, so follow it with a hope of really learning something.
I have had a lifetime of experiences which could have caused any of my genes to mutate. Radon, nuclear testing, -45 degree to 140 degree air temps, Round-Up, cleaning solvents, chemical tests, physical and emotional abuse, extreme fatigue, lack of sleep, thousands of contacts with people with strange diseases, dozens of blows to head, limbs, organs, etc.
But unless you locate the genes that produce the effects, you are just destroying yourself. If you don't have the gene(s), you don't have the crap. So get tested. oldkarl
