Bobbi Kristina Brown went missing after her mother Whitney Houston's funeral Saturday, fueling speculation that she has turned to drugs to deal with an emotional time.

The Daily Beast reports that the 18 year-old went missing after the televised event, sending her family into a panic trying to find her. The Teenager previously was admitted to Cedars-Sinai Hospital after two emotional breakdowns when she heard of her mother's death.

A source tells The Daily Beast, "Everyone was freaking out and calling Bobbi Kristina’s cell. It was so much commotion and activity after the funeral that Bobbi Kristina just slipped away. Ms. Cissy [Houston, Whitney’s mother] was beside herself." A family friend admits Bobbi was in rehab last year.

With Whitney gone, there is now a greater push to get Bobbi Kristina well again. "They tried to save Whitney, and it didn't work. Now with Bobbi Kristina, they fear the same thing is happening again and they won't be able to stop it either. Bobbi Kristina is all Ms. Cissy has left of Whitney. She's so tired, but she's ready to fight again to save her grandbaby."
