Welcome to Psych Central.

That sounds very stressful. Do you have a Dr to help you get the thyroid stuff stabilized? I think it can take some time.
I don't have thyroid problems, but I do struggle with getting medical help because I tend to dissociate pain and symptoms. I try to make regular appts for checkups because of this, though that is hard because a month and a year are the same for me as far as time.
I hope you feel better soon and are able to get your thyroid regulated soon. From what I just read when I looked up thyroid problems, it does seem to affect a lot of things, including memory and other brain stuff.
Feel better soon, and again, welcome to Psych Central.
