It's been a month since Whitney Houston passed away and in her daughter Bobbie Kristina's first interview since the tragedy, she tells Oprah Winfrey, "I'm doing as good as I possibly can at this point. I'm just trying to keep going."

In the sit-down with Houston's and Bobby Brown's daughter, the 19-year old goes on to tell Winfrey:

    "I can sing her music, but to hear it now, I can't. I can hear her voice telling me, 'Keep moving, baby. I got you.' She's always with me. I can always feel her with me. She used to always say, 'Do you need me?' And I said, 'I always need you.'"

What Kristina didn't know was that there were many others in the world who needed her mother too:

    "I just saw her as mom. The first time I saw her as a worldwide icon was when we went on tour. And the funeral. . . She made an impact not only on a few people. She made an impact on the world."

Bobbi Kristina says she wants to do the same -- that she'll "... do the singing thing -- some acting, some dancing."

And she still feels comfort in what she believes to be the presence of her mother in the Atlanta brownstone they shared together:

    "I feel her pass through me all the time. I wake up at night. She would say at 5 a.m. the saints start praying. I wake up now and look at the clock and it's 5 o'clock. I start praying."
