One option is to report her to the respective state licensing board. Even if she does not hold a license you could still report her. You did not mention her credentials. For instance, if she claims to be a psychologist then you would report her to the American Psychological Association state licensing board. If she is a social worker, then report her to the National Association of Social Workers (NASW) state licensing board, and so on.
Virtually all helping professionals, marriage and family therapists, social workers, psychologists, and so forth have a code of ethics. If the code of ethics is violated they risk losing their professional license. You described having a close personal relationship with your therapist. It seems as if boundaries were crossed. If she were a professional social worker, she would have most likely violated the NASW code of ethics. Not only would it have been a violation of the code of ethics, there could be legal ramifications.
You’re doing the right thing by bringing this problem to the attention of her supervisors. It is a good place to start. The next logical step would be the state licensing board. You should be able to find the links to the appropriate resources on the Internet by doing a Google search. I wish you the best. Please take care.
