Was it a cortisol stim test?
Waiting is always the worst...
Yes I had an appointment with an endo. He prescribed thyroid and cortisol tests along with calcium and vit D. I havent got results yet. It may take a week more.
This is a patient forum. We are not docs - we can guess, suggest and guide - but you have to see a doctor or doctors for real help.
With fainting spells, have you seen a doctor - like a cardiologist or an endocrinologist? It can be cardiac, ear (like vertigo) or endocrine with abnormalities in hormones that can interfere with potassium and sodium, among other things. Fatigue is a funny symptom in that it can be related to a lot of things - some can be simple to fix like vitamins - others hormones or neurological issues - so you have to really get a good exam and history and sets of tests.
Have you had any testing?
