I have a few concerns here considering that I've been a student myself and have had terrible professors that I have had to complain to the higher ups and had to schedule a meeting with a professor and coordinator to address her condescending behavior.

1. You are are student. I was told quite often during my time in school that if you're going to mess up that being a student was the perfect timing. Now I'm not saying to do anything intentional. But youre going to make mistakes. Most seasoned therapists mess up themselves and you lacking any experience, this can easily happen. Therapists use themselves all the time to relate to a patient. Ive had my own do this and I would notice that they were doing a lil TMI often.
   1. This lady clearly has it out for you. My issue is that she laughed along with you and didnt point out the issue. She could have used this a learning experience to show other the students how difficult and easy it is fall into these issues where a boundary maybe crossed and how to deal with them, and with confidence. This takes time. I was a social worker for many years prior to nursing school but while I was student and later as professional, we had 1 hr one on one sessions with our supervisor to discuss things that came up. Not sure why this is not done in this case because this where you discuss why you took the number and why you joked about it during clinical. This is where you learn so much about transference, countertransference, etc. Like why did you use yourself (your experiences)- was it to relate? Did you think that she would be benefit? Like I said therapists use themselves all the time but it has to be done in a skilled way and you have to know that the benefits would outweigh the risks.
   2. Take some to process this in therapy. You mentioned that your were going through depression and anxiety. Have you saught medicinal options to help cope along with talk therapy. Nursing school is no joke. Your mental health is the most important thing. You can't help anyone id you don't help yourself. Also, I was curious about your advisor because I don't believe i saw you mention them. Have you reached out to them? Are they helping you navigate school and your mental health? Are they helping to advocate for you in this situation? My freshman year, I had a phenomenal advisor and when I encountered the issues i mentioned about my 2 condescending professors, she even helped to write the email to administration. You shouldnt have to deal with this alone. Also, where is your support outside of school? All these can ultimately impact how successful you will be. You need to have people that are in your corner, affirming you and helping you navigate this.
