Promoted...But Now My Mentor's Gone? What Would You Do?

So, here's my situation: I just accepted a promotion to supervise the team I’ve been a part of for years. The CEO personally encouraged me to apply, so I felt pretty confident—until the day I signed the offer letter. That’s when I found out the long-time manager of our division was suspended and possibly getting fired. I honestly didn’t think the company would let go of someone with so much experience and knowledge. But today, I got the official word—they’re gone. Now, I’m supposed to step into this management role without any senior support above me. I’m feeling totally out of my depth and honestly, a bit panicked. 😬 Some colleagues already know I signed the offer, so backing out would be awkward. But is it crazy to consider rescinding my acceptance? Has anyone else faced something like this? I’d really appreciate any advice or perspective. 🙏 #CareerDilemma #WorkplaceAdvice #PromotionProblems #JobCareer
