My wife chose to get treatment for bulimia last year. Anyone know an insurance co. that'll take her now?

1.5 years ago, my wife voluntarily went to a day program to treat bulimia. She did this out of her own will to handle the problem before it got bad. Now, she graduated from college and is off her parents insurance. We need to get her insurance. Nobody will take her (yet). Does anyone know of an insurance company that will take her on? Either flat our, or evaluate her condition, or make exemptions on that coverage?
