Come on. She’s a media whore. She probably cancelled the tours because her book is not selling and no ones showing up. The threatening to sue is for media attention.
Being sick (nervous breakdown, perhaps?) makes sense.
She strikes me as a morality bully, used to getting her way or at least accolades for putting those she and her fawning media/supporters in their rightful place.
Now she’s on the receiving end, and she can’t handle it emotionally.
