Therapist Lied to Me and I'm Anxious About Confronting Her

It's not against HIPAA for her to ASK your father how you're doing. She just wants to make sure you're okay at home. She has your best interests at heart. Now if she had discussed information WITH your father that YOU told her in confidentiality, it COULD be a violation of HIPAA, but it depends on your age, and on your diagnosis.

Yeah, that's really messed up. I would talk to her about what she did and how it wasn't okay. You should look up the HIPPA rules before if you're in the US so you know what is and isn't acceptable legally. You can always get a new therapist for any reason. You doctors are there to help you and if you think you can get better help somewhere else, go for it. You are not betraying your doctor by going somewhere else. Even if you think it's a silly reason. (This certainly isn't a silly reason though!!)
