How to determine if i have adrenal fatigue?

See endocrinologist: The adrenal makes cortisol and adrenaline, both of which are stress hormones. People who are stressed out and having trouble coping are sometimes persuaded that it’s the adrenal’s fault. This is usually not true. Poor adrenal function is determined by an acth (cotrosyn) stim test, not by simply measuring a random blood/saliva level. See an endocrinologist if you have concerns.
