Bad detoxing reaction

I have always had low energy since I was a teenager and was diagnosed with Hashimoto's thyroditis in 1996.

I was given Iodine to take recently by a holistic doctor before I found this forum and I believe I had a rather bad reaction to it. I ended up having a panic attack last Saturday and I am still dealing with the after effects.

I continue to have very little appetite, but I need some strength to work, since I am self employed ( I primarily trim horse's hooves), my stomach is not working right , despite taking HCL with meals and it may also be reacting to some supplements I have been taking to calm my adrenals down. I also still feel too agitated.

I have seen some comments made here about salt water flushes and taking vitamin C in high doses, which I have done, but have not been able to find more detail about what I can do to support my body right now to hopefully recover a bit faster, so any words of wisdom or pointers in the right direction would be greatly appreciated.

Thank you
