The best way to see if adrenal failure exists is by doing a 24 hr cortisol saliva test done by ZRT. Make sure you are off all kinds of steroids or anything that stimulates the adrenal glands before doing this test (optimally 2 weeks)

If you had adrenal failure you would basically be an Addisonian patient. If i understand right if addisons was your case you would probably be handicapped and bedridden. I've known cases like this in the past. Of course it's not always the case

From those symptoms your biggest issue looks to be candida, parasites, food intolerances . These will all cause stress on your body which will weaken it making you susceptible to Adrenal fatigue. Nothing there suggests to me adrenal failure ie addisons disease, but if you think that might be the case I would go to an actual doctor.

I would look into either Elimination Diet or food allergy test, and get on some kind of candida/ parasite plan. Also know that even if you kill parasites/candida if you do not create a healthier body chemistry in general they will return.
