A source shared that the family is "looking for someone to blame."

"The waking-up process has begun and will take until Tuesday. There is real concern that the part of the brain that controls motor skills may have been compromised, leaving her as either a vegetable or in a wheelchair," a source close to the family shared.

The source shared that the throat procedure should not have been done on an 81-year old as an outpatient. The family believes that the health center is to blame.

Meanwhile, as Melissa Rivers is trying to be upbeat and optimistic about her mother's condition in public, sources say that she is "totally hysterical and is at a loss for what to do (because) they won't know the extent of the damage until Tuesday at the earliest."

Insiders say that Rivers would not have wanted to "be a burden on anyone" and, preferred not to live if the possibility of "a full and active life" was gone.
