I just tested with a saliva test and had low cortisol. I have weight gain, tiredness, hard time sleeping and plain just don't feel well. I have been taking care of my mom who had Alzheimer's for 2 years. She had a massive stroke in April and knows none of us. She is in a VA home now and the rest is out of my hands. I worry about everybody and everything which I know is not good. I guess my questions is, should I try to treat my low cortisol with supplements or do I go to a qualified Dr. who specializes in low cortisol? Any feedback who be appreciated.
