I don't mean to be rude, but you didn't seem to actually say anything in your post

I have also seen research studies that have been done on Holocaust survivors who where diagnosed with Post Traumatic Stress Disorder. (I am specifically speaking of Holocaust survivor who where diagnosed with PTSD, not the ones who did not have PTSD. In the Holocaust survivors diagnosed with PTSD THEIR CHILDREN had low cortisol levels (indicative of adrenal fatigue). In addition, I have seen other studies of Registered Nurses who worked on Pediatric floors or in Pediatric Intensive Care Units and those R.N.'s had low cortisol levels.
And interestingly enough, I just met an R.N. who has a successful practice utilizing NAET, Ondamed, etc modalities in helping people achieve wellness, who stated when I said, I frankly believe my adrenal weakness began in utero, informed me that she has found that SOME pregnant women who have adrenal fatigue have reported that they felt the best they had ever felt in their life during their pregnancy. She said that was because they were utilzing their baby's adrenal glands. Hence, the baby was born with an adrenal weakness.

So, in my opinion there are many contributing factors to the causation of adrenal fatigue........inclusive of mercury amalgams, toxic root canals, lyme disease, genetic predisposition, maternal stress/trauma during pregnancy impacting the fetus, and so forth, in addition to, the aforementioned contributing factors listed by others in this thread, as well as a myriad of other, yet undiscovered causations.

Also, to answer your question, I just recently found a doctor with vast experience treating severe/advanced cases of adrenal fatigue. And for the first time I feel safe with a physician and am making progress, instead of deteriorating. I wish I had known of him when my symptoms first began. Also I have just begun working locally with the R.N. who works in energy medicine utlizing NAET, Ondamed, etc so I look forward to healing.
