Bobbi Kristina Brown is still in a coma, after she was taken off some medications yesterday in a failed bid to bring her back to consciousness.
Having seizures following the medication removal, the doctors had to put her back on the drugs once more.
Speaking to People magazine, a source explained: "This is a horrible setback. Everyone was hopeful that this was the sign that she'd turned the corner. We were so optimistic.
"Bobby is taking this so hard; he was sure this was going to be a good day. But please, everyone needs to pray for Krissi. I don't care what religion you are, or if you have no religion at all. Send your thoughts, your prayers, your well-wishes. Send everything you've got. Please."
Bobbi was placed in a medically-induced coma after being found unresponsive in a bathtub at her Atlanta home on January 31, and it's believed her medical team wanted to bring her round to get a sense of how well her brain was functioning.
Meanwhile, her boyfriend Nick Gordon slammed Bobbi's family for continuing to block his attempts to visit her.
He tweeted: "My heart is full of angry after the Browns have shut me out. They don't even know her. Sabotage.
"I miss her so much. I seem so weak right now. You all have been so supportive! Thank you for everything."
