I have had the blood test to see what my production of cortisone was ; the results -- "no detectable level" of cortisone. Yes, I have been diagnosed with Addison's Disease (very, very low adrenal function) . You have to remember that losing adrenal function can be a slow declining process. You can have many of the symptoms but milder and less frequently when your adrenal glands are stressed but still functioning. At this point, avoiding stress, rest, good nutrition, and relaxation can help the adrenal gland to heal.
