(NBC News) -- Whitney Houston's mother, Cissy, is talking about her daughter's sudden
passing in a new memoir titled "Remember Whitney: My Story of Love, Loss, and
the Night the Music Stopped."
In excerpts obtained by People, Cissy wrote, "I'm angry she died alone, in those
conditions."
The Grammy-winning singer was found dead, face down in her bathtub, at the
Beverly Hills Hilton on Feb. 11, 2012, the night before the Grammy Awards. The
final coroner's report listed the cause of death as accidental
drowning and "effects of atherosclerotic heart disease and cocaine use." The
document also indicated that Houston had cocaine, marijuana, Xanax, Benadryl and
muscle relaxants in her system when she passed away.
"She started partying and she didn't really know how to stop. I used to
wonder what she was doing at night, where she was," Cissy also wrote. The elder Houston also wrote that her
daughter "hid" from her, and that she doesn't blame the singer's ex-husband,
Bobby Brown, for her drug problem.
"I blame him for the way he treated her," she wrote, according to the excerpts published in People, "but I don't blame him for her
drug problems."
