The answer to this question actually depends on a few things.
Where she is practicing,what kind of therapist she is and who she is registered with (registration body), and whether she is legally obligated to mandatory reporting. I can discuss the kind of things that are usually covered by mandatory reporting but the only way you would know exactly what she can/can't do with regards XXXXX XXXXX confidentiality would be to know all of the above details.
Ok, so she will likely be obligated to mandatory reporting as a clinical social worker but the details of this obligation would be specific to NYC. You should be able to look this up on the web fairly easily, or make a anonymous call to the registration body and ask for the details of any mandatory reporting requirements as it is public information.
Psychotherapists often have a registration with a professional body but these bodies often don't have any legal authority and therefore any code of ethics they endorse aren't enforceable. Again, you would need to know who exactly issued the psychotherapy license to know what her obligations are.
If you have had contact with her supervisor you could also contact that person again and ask for clarification of any mandatory reporting requirements and also ask for follow up information as to what action was taken about your initial complaint (this is within your rights).
I hope this has been of some help. Please let me know if you have further questions or would like me to clarify any part of my answer.
