The reason why Park Geun-hye said, "At this rate, I will hold out until the end"

There is a fact that President Park Geun-hye likely shared with a smile.
She smiled while saying, "At this rate, I will hold out until the end."
However, there is a reason why she didn't actually say it.
Because her mental illness worsened somewhat after that, I suspected the reason why she spoke that way.
In other words, as her mental illness began to worsen, I suspected that the President might have been forewarning us.
The conclusion is: The President said, "At this rate, I will hold out until the end." Then, who was it that actually said those words? The police?
