Whitney Houston’s daughter says she’s doing “as good as I possibly can” in her first interview since her mother died last month.

Bobbi Kristina Brown made the comments in a Sunday interview with Oprah Winfrey on Winfrey’s network, OWN. The 19-year-old said she still hears her mother’s voice and feels her spirit: “I feel her passing through me all the time.”

She described her mother as her best friend, her sister, her confidant — “my everything.”

The night before Houston died, Brown says she asked her mother to lay down with her. They spent the night together, and much of the next day.

Brown, whose father is singer Bobby Brown, says she plans to continue in her mother’s entertaining footsteps by singing, acting and dancing.

Houston died on Feb. 11.
