Hi, I really could use some input. I had my cortisol checked by blood test fasting in the morning. It came back normal? Something is not right with me and I wish I could find out what. Is this test normal all the time or are saliva tests more accurate? I am always anxious and now really depressed especially in the morning. I have been taking 20 mgs of Lexapro. What do you all think it could be?
