Whitney Houston’s daughter, Bobbi Kristina Brown, remains on life support after the 21-year-old was found unconscious in a bathtub Saturday -- an accident that echoes her mother’s death. Nearly a week later, the situation is “really dire,” sources told Us Weekly Thursday.

“It doesn't look like she's coming back, at least not back to her old self,” an insider said about the aspiring actress and musician. Her father, singer Bobby Brown, is “beside himself” and is afraid he won’t be able to say goodbye, the insider said.

“He hasn't been able to accept that his daughter isn't coming back,” the source continued. “I think at the moment he's worried that he won't be able to say goodbye. Their last interaction is not the last one he wants to have with his daughter.” 

Some of the countless rumors about Brown and her accident claim her family is fighting, she is brain-dead and they might take her off life support soon. The family denied those allegations in an all-encompassing statement released Thursday: "There is no ‘family gathering’ today that is any different from any other day since [Bobbi Kristina] has been in the hospital. The family has been there since the weekend, so nothing any different today for them to be there than any other day. She is not brain-dead, and the Houstons and the Browns are not fighting."

Even though drugs were not found at Brown’s home after her bathtub accident Saturday, she struggled with substance abuse, Radar Online reported Thursday. The alleged abuse got the attention of ex-boyfriend Zach Jafarzadeh, 24, who tried to save her.

“He was extremely worried about her,” an insider told Radar Online. “She was such a wonderful girl, and he didn’t want her to throw her life away.”

Brown’s accident comes nearly two weeks after Lifetime aired a movie about Whitney Houston. “The View” co-host Rosie Perez said, “The unauthorized biography of her mom must have killed her.”

Houston was 48 when she was found dead in a tub in her guest room at the Beverly Hilton, in Beverly Hills, California, on Feb. 11, 2012. Cocaine use and heart disease were listed at contributing factors to her death.
