Man, this hits hard. I've done so much to protect my part of the org chart from the whims of others and the cost-cutting pressure of the organization at large. My team are happy. Personally, I'm burned out to the level that nothing excites me any more and it's really hard to muster the energy to even do what's needed at the job, let alone drive vision and the team forward.

Take care of yourself. Your oxygen mask goes on first.

My sympathies, I've been there, too. You are not alone. What helped me was to talk about my predicament with peers outside my company at face-to-face meetups. It changed my trajectory and allowed me to find purpose again.
