I managed to recover from a similar level of burnout/pissed-offedness by changing my domain of software development completely. I got out of high-stakes server-side software and into client-side mobile software. It took some effort to pivot, but in the end it was a great relief. In my experience, Apple's slow approval process is a much better problem to have than getting pinged at 3am for any reason.
