She is seriously unhinged, I can't decide whether this is a character/persona she's playing up to or if she REALLY is just that much of an embarrassing head, acting like that isn't normal.
Also, she was only just in Florida... didn't cry at that castle did she?
And, given Benign was filming this goes back to my theory that he deliberately tries to humiliate her and make her look a fool, he gets a kick out of Moon-face embarrassing herself.
