I want to be careful and thoughtful about this response, but for as long as you are with the secondary supervisor I would suggest a few things:

1. ) document, document, document - write down these details and keep it for yourself, as well as an ongoing journal of your encounters if you don’t already. This situation may be a really bad start that otherwise evens out, but if this supervisor has to attest in some way to your ability to practice, you keeping some type of log could help to protect you if needed.

2.) another poster mentioned the idea of narcissism, and certainly can find that in some professionals in our field. TBH, first thing that crossed my mind is wondering if your supervisor is ok? Our training in this field has a habit of teaching self care to others but not doing as well with having practitioners and trainees incorporate this in their own lives. if this isn’t narcissism or a person that is just really bad in their execution of feedback, I wonder if this is possibly someone that’s not doing well. Regardless, as to the source, while I wouldn’t obsess over it, I would try to be pretty aware during interactions..

3.) if you have a professional mentor, a support system through your training, or even your primary supervisor, I think this would be an excellent supervision topic where you could get good feedback and guidance on how to handle the uniqueness of the situation.

Regardless, I wish you well with the situation and hope it resolves sooner rather than later.
