the link between the thyroid and mood/mental states is well documented. A very quick google search - "thyroid", search within results- "stress" netted a gazillion results- here's one:

That article focuses on mental symptoms being associated with thyroid conditions, a rather mechanistic viewpoint, i.e.- "mary was hypothyroid therefore she got depressed". It's not so simple as that. Very true that mental states influence our physical health... what came first? In your case, absolutely, stress, hell, way more than simple stress. Life-altering changes. You have lost your mom, a source of unconditional love:)
I don't think that there is anything more devastating than the death of one's mother. And having to take care of the business of death is a double whammy- how completely exhausting. I'll bet that you have not had the time or the space to grieve. Not that simple grieving will get you past this- but it's a start.
Jeez, I remember when my mom died, the funeral director was showing us coffins, my mom's husband asked me which one I liked. I blurted out "I don't like ANY of them!!!", and burst into tears.
And now, having to deal with so-called nutrition experts(with obvious $$$ interests). Sheesh.
As far as THAT goes, get thee to

. They maintain a listing of
Iodine literate docs. So do your homework as far as that goes and when they try to intimidate you, have your references at the ready.
And- you need to take some time for yourself and try to work through some of your feelings. One thing that I did, it was not a concious choice on my part as far as trying to heal myself- I just didn't want anyone to forget about mom- was that I went through a bunch of family photos, played with them in photoshop and made postcards and a calendar. It was really cathartic, in fact one night when I was sitting at the computer and missing my mom SO MUCH, the scent of her perfume filled the air, I'm getting teary-eyed thinking about it now 8 years later.
Nothing will replace your mom, that's a huge loss. You need to figure out how to deal with the loss. It won't be easy, but you have to acknowledge this now.
