I think maybe you are looking in the face of a break-through with this flashback and you are scared to take the next step. Her speaking to the supervisor could be the thought of a different type of therapy for you; or something she may feel she needs guidance with.
Speak from your pain level shoez, she is not tired of hearing you or will condemn you in any way. She's heard it all before shoez and you are a worthy person who just happens to need help. Go for it shoez. Nobody promised it would be easy going through all the victimization you have had....just know that you can and will have victory for yourself in due time. Hang in there sweetie...don't worry about your t doing anything but wanting to help. So let her! hugs, bj
