Doctors had to put Bobbi Kristina Brown back in a coma Wednesday, after attempts to take her out of it resulted in "violent seizures," RadarOnline.com has learned.
"She was taken off the drugs, but she began having violent seizures," the insider told the magazine. "She is being put back into a coma."
"Everyone was hopeful that this was the sign that she'd turned the corner -- we were so optimistic," the insider said.
Bobbi Kristina's father Bobby Brown was "beside himself" in the wake of the unsuccessful effort, 27 days after his daughter with the late Whitney Houston was found face-down in a bathtub in her suburban Atlanta home Jan. 31.
"Bobby is taking this so hard," the insider said. "He was sure this was going to be a good day."
