The notes Paula Broadwell sent to Jill Kelley were far more sinister than previously reported and seemed like the rantings of someone “clearly unhinged,” a close friend of Kelley told The News Monday.

“This wasn’t just a catfight. Any normal person who got emails like that would have immediately called the police,” said the friend.

She said Kelley read her the emails when she called, panic-stricken and seeking advice in the days before the scandal became a stunning public spectacle and led to Petraeus’ resignation as CIA director.

The friend, who did not want to be identified, said Kelley saw the emails as death threats, specifically one in which Broadwell vowed to “make you go away.”
