Hi NayNay,
Hope you don't mind me chiming in here, but, like others have suggested, I recommend getting your blood work done, as well as getting your hormone levels tested. I have been battling with adrenal exhaustion for the past 2 years. The only thing that uncovered the problem was by taking a saliva-based hormone test in addition to the standard testing performed by my doctor. I was run down, not able to exercise, ALWAYS tired (chronic fatigue), emotionally drained, and gained 40 pounds before I even went to the doctor to get diagnosed.
Many doctors won't test your adrenals or reproductive hormones, and if they do, they usually do so by blood, which is NOT the most effective way to test your adrenal glands. You'll need to do a saliva-based test, which is collected 4x/day. I recommend ZRT labs for a hormone test; the complete female panel + vitamin D is a great one. It's expensive, but so worth it!
Be forewarned: it does take time to rebalance your system, but it can be done. I'm still going through my rebuilding process. I was in pretty bad shape, and I'm still working on getting back in balance after 1 year of treatment.
PM me if you'd like to discuss further.
Good luck,
