Marilyn gave you good advice, read the book and educate yourself as much as possible. You symptoms are bang on for adrenal fatigue and you are not alone. The bad news is that it can take anywhere from 6 months to 2 years to heal depending on the severity of your fatigue. The good news is, as a result of your predicament you have an opportunity to learn more about the true nature of health than your family doctor and once you acquire that knowledge you can use it to remain happy and healthy for the rest of your life!
I've been messed up for about 14 months now and just got a proper diagnosis 3 months ago, so I still have a long way to go! Stay strong and positive and visit this forum often so you know that you are not alone in your fight.
