Suitable-Tomatillo-7's journey

I'm currently facing a challenging situation at my job as a Director. My previous manager, who was the Chief of Staff, was unexpectedly fired last week, and now I'm reporting to the HR Director, who seems to have a personal issue with me. From day one, her communication has been aggressive, and she questions my work despite not being familiar with my role or department. For instance, after I recently experienced a death in my family, I reached out to her, and instead of offering support, she focused on why I might want to leave and what tasks needed to be done. This has left me feeling isolated and unsure about my position. The older colleagues in the office already undermine my authority due to my age, and with HR seemingly against me, I feel like I have no one to turn to for support. My previous manager was always supportive and never raised concerns about my performance, but now it feels like I'm under constant scrutiny. I'm worried that this new arrangement is a setup for my dismissal, even though some believe the president still has confidence in me. I'm trying to navigate this difficult dynamic, but it's tough when my new manager lacks knowledge about my department and seems disinterested in doing her job. I've been advised to document everything and keep a record of our interactions, which I hope will help if things escalate further.
