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.

A diagnosis is burden enough without being burdened by secrecy and shame.

It's like if people don't see you on TV every day, they think you're in cryogenics somewhere.

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.

It may feel like the more you know about depression and the many forms it can take, the more questions you have. That's how I feel.

My son has been known to throw a book at the television set when he called for me to come play and I was obviously busy in the box. But I'm told that children of television performers grow up thinking that all mommies or daddies work on TV and that it's no big deal.

'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.
