While her condition remains grim, "there hasn't been a change in the past week," says a family member. "Nothing at all. It's not like her kidneys are shutting down or anything. There hasn't been any change."
Brown, 21, was found unresponsive in her bathtub on Jan. 31.
While she remains hospitalized, members of her family, including her father Bobby Brown and grandmother Cissy Houston, have been maintaining a constant vigil by her bedside.
"I think we're all getting on each other's nerves now," says the family member about the relatives that have been frequenting the hospital. "Everyone's under a lot of stress. Bobby doesn't want any part of the drama; he's there for Krissi, not for us."
One person who hasn't been allowed to visit Brown at her bedside is boyfriend Nick Gordon, who has long had tension with members of her family.
"We don't talk about him," continues the family member. "Bobby doesn't mention him at all, ever. We're trying to give positive energy around Krissi, and Nick is not positive energy."
