Adrenal Insufficiency :: Interpret ACTH STIM Test Results

I am 38 Year Old male, Have been an athlete and or worked out since the age of 12 (super active). For the last 10 years or so I have been super fatigued/tired, don't recover well from exercise, terrible reactive hypoglycemia, muscle twitches, tan year round (i used to be white/pail as could be, now I carry at tan year round) short temper, sleep like crap. I can't seem to handle heat or a ton of direct sun. I will get sick for a day or 2 nauseous/fatigued/headache (it is not water usually i will drink 2 liters of water while out hiking for the afternoon.

I have taken 3 different Saliva cortisol test and all 3 looked the same, cortisol was in the tank upon waking and slowing rose throughout the day. The complete opposite of what it should look like. I finally talked my doctor into doing an ACTH Stim test. I have only got back the Cortisol results at this point, But they are very interesting??

From all that I have read on intercepting ACTH results your baseline Cortisol should double at 60 minutes. According to this test is should be >18 at 60 minutes I only rose 8!!! Please see results below.

Baseline Draw- 19.7, Standard > 5

30 Minute Draw- 26.4, Standard >7 Above Baseline Result, JUST UNDER BY .3

60 Minute Draw- 27.7, Standard >18 Above Baseline Result, 10 UNDER THE BARE MINIMUM IT SHOULD HAVE RISEN!!!

I am a little confused on how to interpret these results?? Like I said I should have the rest of the numbers in a few days.
