I'm experiencing a version of this. I'm burned out at my job, but my life circumstances and personality keep me from looking for another one.
What I have done is strictly confining my job to have a minimal impact on the rest of my day and concentrate all my real effort in a particular hobby. I have gotten decently good at it in about a year, and made myself known in a few communities where the top practitioners hang around by sharing my results or giving feedback for others.
The result is that now I'm continuously rejecting commissions and offers that would turn it into a second job. I don't want that, but just getting asked feels so validating that the effort is completely worth it.
