I've been there. What worked for me was talking to my manager, and arranging to unplug by taking a significant amount of time off. For me, this was two weeks initially, which I extended to three. IMO, three weeks is the minimum I would consider taking if I get into this state again. If your manager is a good one, they will support you. If your organization is a healthy one, your team will understand and empathize. Burnout is real, and, in my experience, it's unlikely to resolve by staying the course.
