Just to back up Sannah... it's awful that people are saying this to you and you really do need to talk about it. Your T should protect your confidentiality, so even if your relationship to these people makes it obvious who they are even without names, your T can't do anything about. You could even quiz her about what she would do if you told her about something that could get you in trouble if it got out.

No one deserves that kind of verbal abuse. What you do deserve is the comfort in the safety of the therapeutic setup, in which you can talk about it and deal with it.
