I agree 100%. Adrenal Fatigue is the result....not the cause.
In fact, my testing from Integrative Psychiatry in the past has shown my Epinephrine is LOW, even though I still had lots of anxiety.
And again, excess epinephrine is not the only cause of anxiety as I pointed out.
And if we take this a step further anxiety can still be epinephrine induced despite low levels. Again the trigger is epinephrine not balanced by sufficient acetylcholine. It is like how women can develop estrogen dominance after menopause despite declining levels of estrogen. Even though there is lower levels of estrogen there is still insufficient levels of progesterone to balance the estrogen.
