You could be suffering from depression and/or you could be pre-menopausal. I am a couple of years younger than you and my gynecologist initially diagnosed this in the summer of 2000.I had my doubts and reluctantly took the brochures he handed me on this subject. I had planned on throwing them in the trash when I got home. Fortunately, I didn't, and found out that I had many of the symptoms. The bottom line here is that your GYN can help you! Good luck!
