Well on paper everything does seem normal. I suppose your morning cortisol could be a bit higher but it's not definitively low enough to cause your symptoms.
Speaking about your symptoms; what do you mean by brain fog? Do you feel that this ordeal affects your working memory?
I still feel that the majority of my symptoms revolve around dopamine; low libido, diminished ability to enjoy things, low drive/motivation, feeling disconnected from others. I do not have the physical symptoms that you have.
Also, your theory that raising E2 leads to a permanent worsening of this condition does not seem to apply with me. During these past weeks I have tried higher doses of HCG and did not notice a permanent change for the worse. I did however notice that the elevation of E2 did not cause the same effects that it once did.
From the literature it does seem clear that you need healthy amount of estrogen for proper dopamine release. Also it is clear that estrogen is involved in the thing's that you mentioned - like sebum production.
So if I look at my situation the most plausible hypothesis would be that the overuse of aridmidex caused some sort of dysfunction/damage to my dopaminergic neurons. By looking at the past 6 months I would cautiously say that my body is recovering from that.
Your case seems a bit different - with all those physical symptoms. By looking at your history and symptoms the hypothesis you present could be a possibility. Of course - like you stated - its pure speculation at this point.
May I ask how are you planning to proceed with your condition? You once mentioned something about the use of HDAC inhibitors. On paper they do seem to do what you are hoping to accomplish:
