If they are paying her and she’s working as a social worker, she is bound to privacy laws. There may be a conflict of interest here. However you have the right to ask to be referred to another person if you feel uncomfortable.
Yet I agree to give it a try. Just be yourself.
It could also be good that she knows your family and whatever you tell her, for the most part (unless it has to do with harming someone or crimes chas v’shalom), must remain private on her end.
So you’re free to be you and tell her what you’ve confessed to us here.
B’Hatzlacha as well 🙂
