Hi Mozza, ooh rppfl has a good suggestion. I'd go with listen and validate, then say there is nothing wrong with current godparents (not stridently but just calmly state it) and if she still puts up a fuss go with rppfl's suggestion. Genius. Compromise.
I'm no doctor, but the symptoms you listed don't really sound like a serious disease to me. I'd say these behaviors are typical for the WAS. She does sound like maybe she might have some issues with anxiety or ADHD, accounting for the hyper talking and insomnia. But does it even matter? There is NOTHING you can do about it. Even if you are 100% right that she is bipolar, telling her that will just drive her away. You cannot get her to see your perspective at this time.
My WAH also did a lot of stupid and crazy things around BD. He is starting to mellow out after a few months. The fog drives them to crazytown... try to let it go. If you want to think of her as bipolar or ill or completely insane, go ahead, it may help you to deal with the wacky behavior. But it's pretty much a waste of your time to obsess on it as there is nothing you can do about it now.
