Cristina Saralegui recently returned to Univision after having been fired a few years ago.

The TV host, who has a new book out, spent a few days on "Despierta America," but she returned because the people who fired her are no longer at Univision.

"The people who fired me are also gone," she said. "But they weren't there 21 years; they were only there for about one or two years, and in that time, they ruined what we had built in our house. Thanks to God, these people are no longer there, so I grabbed the phone because you have to leave your pride at the door."

She said she spoke to her good friend, Alberto Ciurana, who is now the president of the company, and explained that her publicists were having a hard time getting through to promote the shows. He told her to come whenever she wanted.

Saralegui said she wrote the book because it's an honest guide, which makes it very much like her.

And she explained that she didn't open up about her son being bipolar before because it's his life, and she didn't feel it was right for her to speak about it.

"Of all things that have personally happened to us, this is obviously the worst," she said. "As a mother, seeing your son, your baby and the only son for Marcos and me, that is so sick to the point that he wants to kill himself, I wanted to die. ... And I had to go record, work, laugh and dance after dealing with my son. I would go home and cry, cry, cry."

She said that it did drive her to drinking, and she was killing herself. It wasn't until her husband spoke up that she decided to make a change.

And though she's doing well these days, she doesn't think she will be returning to Univision or Telemundo.
