Yep, those are definitely signs of burnout. This happened to me this time last year. For me, I stopped coding and started building things with my hands (I renovated a house). The biggest problem with coding is the feedback loops. The endless minutiae of problems/bugs that must be fixed, the large holes (metaphorical) you must deep dive into to that make you lose sight of the origin and the end of the project.

Really if I think about it, the movie Office Space nailed it. Go do something else, coding will always be here.
