Why would you want to continue to work with these people? You're divorced, and it's not a positive work situation, given that you're neck deep in family drama. They do not have your interests at heart.
Redouble your efforts to find another job. You may need to retool your resume and look at what you offer external employers. Think about consulting a professional resume and outplacement service for advice on how and where to go about job hunting in the digital age, and brush up on professional networking, your professional image, and interviewing skills. You might also consider a stress-based medical leave or a severance agreement in consultation with an attorney. Also consider going back to your divorce attorney to file for spousal support, if necessary. (Hey, your husband had this it coming.)
