I am a graduate student who shares a health care plan with my father, as his dependent. I also see a family practitioner who serves as a doctor to both myself and my parents. During an appointment, I divulged certain information to my doctor. Some of this information was regarding drug use and some of it was general health information. Upon being questioned by my mother during her appointment on a different day, my doctor disclosed everything I shared with him to my mother. None of this information seemed like it was relevant to her. I did not talk about violence/violent thoughts/anything even related to that.
As a consequence, this has negatively affected every part of my family life.
What are my doctor's legal obligations to confidentiality under these circumstances? Did he violate those obligations? What are my options for recourse?
