and with the Furies at your door! the rolling and off and hitting of heads is sooooooo standard, but usually when someone really IS there to see it.
not to alarm you, i have done this, and SPOKEN WITH the imaginary people, made the coffee in a total zombie state, and then come to myself.
you may be able to appease people by making a great show of taking walks (not sure if your C would allow it) or doing something that equals "making an effort" to them. Gosh even a haircut they like!
it could win you a little latitude with stuff you just CANT change, and will have to learn to live with (a little HELP here??)
laughing about it, and wising off to them will help:
"No, Mom, it didnt go away. I woke up with the world's dumbest disease AGAIN today."
"Gimme a minute, my little voices want something"
one day you will realize they are joking to DEFEND you, that was a sweet sweet moment for me.
