We broke the story … many people close to B.K. feel she has allowed some of Whitney’s enablers to get heavily involved in her life … and if Bobbi doesn’t cut them out soon, she’s doomed to the same fate as her mom.

Those people — sources say — include various individuals who knew about Whitney’s problems, but didn’t take action when the singer’s life was spiraling out of control.

Bobbi’s problems were highlighted during the premiere episode of her Lifetime series, “The Houstons: On Our Own” … which featured 19-year-old Bobbi slamming wine and slurring. The episode was taped a few months ago … and our sources say the boozing has only gotten worse since the show wrapped.

During a tease for an upcoming episode, an emotional Pat Houston suggests taking Bobbi to California … where Whitney received treatment from a drug counselor before she died.

Sources close to B.K. tell us … they DON’T WANT Bobbi to see the same counselor, because they feel he did not help Whitney … and will fail again with Bobbi.
