This situation is one of the many reasons you are paying an agent 10% and/or a manager 15-25%.
THEY need to get on the phone with the producer/director/casting people and tell them to "Shut the f--k up" using just those words since in the long run the show's people will look even worse than producers look which is pretty crummy to start with.
YOU take the high road. Keep your precious mouth shut in public and in private.
In the meantime get your butt in front of an audience. In a show or a cabaret act. Either one, although make sure you look good. Real good. Spend some money and get some charts (and a press agent for the gig) and put yourself in front of a crowd of professionals.
And never allude to this until you write your memoirs in which this will be but a footnote.
When you're alone, play the cast recording of Applause, the first act finale:
"Welcome to the theatre.
To the magic,
To the fun.
Where painted trees and flowers grow,
And laughter rings fortisimo,
And treachery's sweetly done.... etc."
"If my life weren't funny, it would just be true. And that would be unacceptable."
--Carrie Fisher
