Sounds like you've had different as to your q.
Just wanted to point out the reason for the differing opinions is prob bc you used the word 'burn-out.' when ppl say burn-out, they refer to 'adrenal fatigue, ' which most mds agree does not exist. But if a dr thinks u r asking about adrenals not working, then yes, adrenal insufficiency
does exist, but doesn't happen bc it burnt out/got tired.
