Please HELP! What do you think of my cortisol levels?

I have been experiencing fatigue and stress. The MDs lack any ideas and reject saliva tests. The lab (ZRT Labs) that did my saliva tests stated that my cortisol was low to low normal. I have been working on this from a variety of angles. The feeling of constant stress is the worst and the lack of stamina adds insult to injury.

I was wondering what you and others think:

Cortisol AM saliva 2.9L ng/ml Range 3.7-9.5
Cortisol noon 0.9L ng/ml Range 1.2-3.0
Cortisol Evening 0.6 n/ml Range 0.6-1.9
Cortisonl Night 0.5 ng/ml Range 0.4-1.0

Progesterone was 61Lpg/ml Range 75-270 Premenopausal
Ratio:Pg/E2 28L Range Optimal: 100-5000 when E2 1.3-3.3 pg/ml
DHEAs 21.8 ng/ml Range 2-23
Testosterone 20 pg/ml

I had an ACTH test by an endocrinologist. However, I learned the ACTH was borderline and he wanted me to go back to do another one, just to make sure. I don't want to go through the experience again.

What I have is:

Cortsol, Total Serum 8.4 ug/dl
ACTH plasma 15 Range,46-pg/ml
Cortisol, total serum 15.6 ug/dl
Time +30 min
Testisterone Rotal serum, 31.0 ng/dL

Apparently this was a low dose ACTH stimulation test which should increase from 8.4 to 15.6. the threshold is 18.

My testosterone was:

ESTRADIOL, SERUM: 113 (NL levels: 27 - 122 pg/mL)

SEX HORMONE BINDING GLOBULIN: 69.0
% FREE TESTOSTERONE: 0.8
TESTOSTERONE, FREE: 2.5
TESTOSTERONE(TOTAL), SERUM: 31.0

I have no guidance what to do next: should I follow a carb free diet?, should I eat a big meal in the morning, no dinner, should I eat more meat? Less meat? No meat? Eggs?No eggs? Exercise? How much? this is tdhe tip of the ice berg of what to do or not.

If you or anyone have recommendations or perspective on these tests, please let me know.

All the best to all,

Growing Gratitude
