Jinxy (and Beth), your stories sounds like soooo many of ours. I wouldn't be surprised if you react the same way to reading SPII as many of us with burned out adrenals did. It's like she's talking to you personally. So much begins to make sense.

Low cortisol and low adrenaline states are the same in symptoms. In fact, she refers the reader back to the low adrenaline states when discussing symptoms of low cortisol.

As Tig mentions, there's lots of info on the internet about adrenal fatigue (or burned out adrenals, same thing). Here's another good site you can look at until the book comes in:
