Two days after Bobbi Kristina Brown was hospitalized after being found unconscious at her home, a source close to the family tells PEOPLE she “remains unresponsive” and is on a ventilator.

Another family source told PEOPLE late Saturday that her recovery would be a miracle. “Everyone is holding hands, praying, hoping for the best.”

According to the police, Whitney Houston and Bobby Brown’s 21-year-old daughter was found facedown in the bathtub by her husband Nick Gordon and a friend in their Roswell, Georgia, home on Saturday morning.

Gordon “started CPR and a police officer took over life-saving saving measures until an ambulance arrived,” the Roswell Police Department said on their Facebook page. Brown was then rushed to North Fulton Hospital, where family and friends stood vigil.

“It’s expectedly a very tense time for the family,” says the source. “And they are closing in on [protecting] Krissy.”

On Sunday, Bobby released a statement through his lawyer, Christopher Brown of Brown & Rosen LLC, saying, “The report that Bobbi Kristina Brown has been taken to the hospital in Atlanta, Georgia, is accurate. No additional information will be forthcoming.” “Privacy is requested in this matter,” the statement continued. “Please allow for my family to deal with this matter and give my daughter the love and support she needs at this time.”

“It’s been a difficult time for Bobbi Kristina, who’s struggled in the years after her mother’s death,” a source told PEOPLE. Brown’s incident comes days shy of the three-year anniversary of Houston’s death on February 11, 2012, when she was found in an a bathtub in Los Angeles after an accidental drowning caused by a combination of drug use and heart disease.

Brown “has been vacillating between extremes for a while now and is fighting grief and demons of her own creation,” the source continued.”The loss of her mom and her intense craving for attention of any sort are just the tip of her mountain of issues.”

Brown’s cousin, Jerod Brown, told Sky News on Saturday that she was “doing fine.”

“She’s pretty good right now, she’s around family,” Jerod said. “We’re just praying for a speedy recovery, that’s it.”

When asked about the upcoming anniversary of her mother’s death, Jerod said Bobbi Kristina had been “in good spirits.”

“Of course she goes through the grieving because it’s still fresh, but other than that she’s doing fine.”

Jerod also shared his family’s thanks for the outpouring of support for his cousin.

“Again thank you all for your prayers & constant support! #BrownFamily,” he Tweeted.

On Sunday, Jerod asked for prayers for his cousin on his Facebook page, noting that “now’s not the time for negativity”
