benzometoo- Sorry to comment late. Just saw the post. I have Hashimoto's thyroid issues and have kept tight rein on levels during WD. Full panel with T3 and T4 levels is necessary to figure out what's happening as the TSH thyroid stimulating hormone can be within normal range while out in the body, it's T3 T4 are low. Here's a great reference for what/why of tests.
https://www.tiredthyroid.com/optimal-labs.htmlThyroid is affected during WD due to prolonged stress on many systems. A chemical called orexin rises during long stress. Too much causes hypervigillance and insomnia. It affects the HPA hypothalamus pituitary axis- the feedback loop for the thyroid.
Yes anxiety/depression can be related to thyroid, primarily the active form T3. Supposed to be the body converts as needed, but due to genetics and other cofactors missing, some people are poor converters. I order a T3 med from AllDayChemist and buy T4 locally. My doctor is pleased because the combo keeps stuff optimum.
Back to orexin- It has been found with both as well.There's some genetic predisposition to have low/high. levels of it. Although this is entitled "How to Increase Orexin" the bottom 1/3 tells how to lower it too.
https://www.narcolepsysupport.org/forums/topic/how-to-increase-orexin/If I wer guessing, I'd lean towards too low thyroid and too high orexin due to WD. I have lots of posts for supplements I've used. Might want to check it out. Best of luck.
