I had PND over 2 years ago when my son was born, and it still seems to manage to rear its ugly head. At first I didn't believe that it was PND, but even my doc suggested it could be. I have days when I am SO tired that I just can't function, I feel overwhelmed by the simplest things, feel miserable for no reason, and normally I'm a pretty happy person with lots of energy. Does anyone else feel that even after a few years?
