Oh, and a sign of progress? You were able to throw your hands in the air, be exasperated, but completely unsurprised that your family is still just as screwy as always. And then you moved on with things, venting about it in a healthy way here with others in the know.
I'm really trying to pick my battles nowadays. I try to view them with compassion, from a great emotional distance. My suggestion is to just document and keep in touch with your lawyer about their crazy antics.
