This is a serious, serious condition that is also called postpartum psychosis. And that's where, literally, you get so bad that you end up either hurting the baby or killing yourself.

My mother has always been my role model, and I believe my survival in the entertainment business is in large part due to my desire to be a strong woman like my mother. She is my hero.

That's what it is to be a grandma. All fun and no stress.

When I did 'Dancing With the Stars,' I got literally thousands of emails from people saying, 'We relate to you. I've been divorced. I'm raising kids on my own.' Or, 'You've had money. You've lost money.'

I didn't know my mother had it. I think a lot of women don't know their mothers had it; that's the sad thing about depression. You know, you don't function anymore. You shut down. You feel like you are in a void.

When I look in the mirror, I see my late mother: I have her nose, her dark eyes - I call them chocolate eyes - I have her colouring, and my hair is greying the same way, although I use colour and she didn't.

I don't claim to know everything. I claim to be a seeker of knowledge.
