Sources close to the troubled teen say she was ‘getting high’ after the ceremony — do YOU think Bobbi will head to rehab to try to get clean?

Bobbi Kristina Brown has been so shaken by her mother Whitney Houston‘s shocking death and funeral that she is reportedly using drugs once again.

The ceremony, which took place on Feb. 18 in New Jersey, seems to have pushed 18-year-old Bobbi over the edge, The Daily Beast reports.

A source close to the family says Bobbi snuck off after the service, citing a need for private time. But when she left, family members were concerned about her whereabouts.

“Everyone was freaking out and calling Bobbi Kristina’s cell,” says a family friend. “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.”

Unfortunately, drugs were thought to be in play.

“Cissy and others won’t admit out loud that Bobbi Kristina has a drug problem,” the source said. “But they know it and have been trying to keep her straight even before Whitney passed. But losing your mother and the life you’re accustomed to all in one day is enough to send anybody off the deep end.”

As the family began to admit that the disappearance had been due to her “getting high,” they determined that rehab is the only feasible option. As previously reported, they plan to send her to treatment as quickly as possible.

“It’s a horrible situation for everybody,” says the source. “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.”

We wish Bobbi Kristina the best in her recovery.
