I had a similar profile to yours in February this year but with 3 of the results higher than range. I had DHEA tested too and that was below range. My private dr gave me DHEA capsules and adrenal support capsules.
Have you had a lot of stress in your life recently? I had been very stressed before that test. I had also had a short synacthen test a few days earlier (ordered by the NHS endocrinologist). I now believe that the injection of hormone from that test in addition to the stress caused the high readings. I didn't know at the time how to handle the stress and just tried to work through it.
You can deal with the high cortisol by taking time for yourself, reducing any stressors as much as possible. Eating a healthy diet and not over exercising.
I am currently reading an excellent book on Amazon kindle, "Adrenal Fatigue, cure it naturally" by Carmen Reeves. It's not expensive and the information is extremely helpful.
Basically the adrenals will churn out a lot of cortisol to help you cope with the stresses of life, but if the stress becomes chronic, you will use up all of your reserves and then you will suffer a crash (adrenal exhaustion).
I have just suffered the crash and am now working on recovery. My cortisol levels in the test I took 2 weeks ago are virtually non-existent. It will probably take quite a while for me to recover now because I didn't take action earlier. I hope this is helpful and that you can avoid a crash.
