my mother was exactly the same
during an episode, for example, she used to say to someone " well she's never done this before, she's such a bad child"
find something useful to do was another one and " were you born human"
I remember when I was first diagnosed bipolar, my mother said oh, so you don't just act weird, now you've given it a fictional name, too
I'm so glad I don't live their now. it was unhealthy
