Yikes, an eating disorder is not something to fuck around with during pregnancy!
I'd talk to an attorney, or if you are not comfortable with that, a womens' advocacy group, who can point you in the right direction for good legal advice. If you have your anxiety and eating disorder documented by a medical professional (which, no doubt, you do by now with pre-natal visits?), that may be in your favor; but, again, that is something that an attorney familiar with your state's laws can help you with.

Here's somewhere to start anyway:
National Women's Law Center: Stay Connected with the National Women's Law Center

Edit: One of my acquaintances works for a womens crisis center as a legal advocate. I will ask her next time I see her how this is handled in my state. Although she deals more with women who are in troubled times, that must be a subject that comes up frequently. I'm also thinking that since that will be the only substance, they hopefully would not be bothered to go through the expense and disruption of any action on it?
