That's exactly how my close female friend was for decades. Her HMO endocrinologist was close to useless as you indicated. A functional medicine doctor was better for hormone balancing. She decided to get her silver-mercury Amalgam fillings removed and detox using Cutler's conservative heavy metal protocol. Her 4x saliva cortisol results were similar to yours. Cutler's suggested supplements for her symptoms were remarkably helpful. They've nicely taken the edge off of many of them. Her head is also much clearer in stressful situations. Her mood is also more consistently pleasant. It is quite nice, although still not quite in the normal range for her age.
Check out the supplement list in my previous post. Much more could be said
