Endo is having me do a 24 hour urine test as well as a coritsol blood test. (It is recommended that I do the coritsol blood test at 8 AM on testing day.)

Does any one know what these tests will or will not prove? What if I am still within normal range? I know I am jumping ahead...

I have been so tired lately. Not to mention that I feel that I am losing my mind. No thinking capacity. And NO memory. HELP!
