Not getting much better with natural approach

I was pushed into an adrenal crisis in March after taking Iodoral. I had a feeling my adrenals were fatigued and I have Hashimotos, but I had no idea that Iodoral could cause something like this...

Since then I have had no coffee, black or green tea, no refined sugar, have been drinking salt water to support the adrenals, eating the right diet for adrenal support, but no matter how hard I try, I do not seem to get over the hump and some supplements that are supposed to support the adrenals seem to stress them out even further, like Vit C, magnesium, etc. I have been taking a high quality adrenal cortex supplement (6 tabs a day, increased slowly to see if it would help), licorice, Rhodiola, Ashwagandha,
Ginger. I seem to tolerate the herbs best, but have the feeling the adrenals also do not quite agree with the Ashwagandha.

Last night the adrenals acted up again and I really felt badly stressed for no good reason and I had to resort to putting hydrocortisone cream on my forearms and that finally helped. Does this mean I should be on hydricortisone therapy for a while?
