Funny when you feel pretty much okay but anxious and tired. Fever drives him crazy but never feels feverish
I would listen to your symptoms and actually think he has the opposite of low - but high cortisol aka Cushing's syndrome.
That fits more with no sleeping, high blood pressure low T and elevated cholesterol not controlled by meds. I have friends exactly like that. Anxiety is typical.
Cortisol normally changes during the 24 hour day. It wakes you up and puts you to sleep. So it can be super low and then higher - but with the shift work the doctor has to test him at the proper times to catch the right times for your husband. Just the fact that at 1 hour after he wakens he is low shows he has a loss of diurnal rhythm - and I had that with my Cushing's. I had low days and high nights - it made my life pure hades.
You need to get the doctor to test ACTH and cortisol - and probably saliva testing would work for your husband so he can test at different times to catch the highs. I would also check out renin and aldosterone - those play a part in blood pressure.
I know I got really weird things with mine - including a bleeding disorder and my immune system just went away and I was sick all the time. Everyone is different - some people get soft bones, some sick, some crazy...
