I went through the exact same thing as you, and I needed some time to explore different ways of living. I tried being a drone pilot, a kayak guide, and a paddleboard instructor and learned a lot in the process.
After those forays I designed and built a trailered coffee from scratch and now I run it on a public park that overlooks the ocean.
I am more fulfilled than ever, I can pay my bills, and I get to do WAY more "real" engineering than the bureaucracy of my past life at FAANG ever allowed for.
