It does make sense and I do think she has some sort of personality disorder/hero complex that others have described along with being quite controlling, bullying & manipulative with her own behaviours.
I’m not so sure that she’s scared that the lies will catch up on her as I really think she believes her own lies and that she is 100% right. Even her Insta post yesterday & the comments under it- she’s loving all the sympathy and milking it for all it’s worth. And I think she truly believes what she is typing. People who want paypal transparency are evil bullying trolls and haters
If she thought there was anything wrong with her behaviour she’d have removed the status about the disabled child (or, even better, not put it up in the first place).
