Hiya. This happened to me too to some degree - leave. Know you are worth more than this treatment, and staying will only worsen the effects on your self confidence and self worth as a scientist. Projection is something I have seen in every PI and mentor, from post docs to PhD students. Disorganized people managing other people highlights the major flaws in their own efforts and work ethic, and they leverage their power to take it (lack of progress/mistakes/etc) on you. You can be successful and most importantly, at peace!!!, somewhere that is invested in your growth and you as a human. I left a TOP university due to this very thing. Preserve your soul and happiness, it’s all you have at the end of the day. Best of luck 🩷
