The most likely moment for something incredible to happen to me was the moment I was most certain nothing ever would.

About the time I turned 50, I experienced the profound biological change that often accompanies women at that age. Also, I put two kids in college and lost both of my parents, so I'm no longer somebody's daughter.

I came back to work when my children were two months old. At that early age, they seem to have little awareness of anybody but their Raggedy Ann dolls, so it wasn't a matter of them missing me. I was missing them.

'Good Morning America' exploited Joan Lunden's pregnancy, but you won't see me bringing my babies on the air. The only reason I'm talking about the babies at all is that they've been with me on the show since I became pregnant. After a while, I had to acknowledge this pumpkin tummy.

Sometimes it takes the better part of a lifetime to find out what your passion is, but in my observation, if you do, it might be the best part of your life.

Most of us in the baby-boom generation were raised by full-time mothers. Even as recently as 14 years ago, 6 out of 10 mothers with babies were staying at home. Today that is totally reversed. Does that mean we love our children less than our mothers loved us? No, but it certainly causes a lot of guilt trips.

When I was diagnosed with bipolar disorder the year I turned 50, it was certainly a shock. But as a journalist, knowing a little bit about a lot of things, I didn't suffer the misconception that depression was all in my head or a mark of poor character. I knew it was a disease, and, like all diseases, was treatable.
