I came back from work and now I actually feel great.
But I literally did nothing on that time off. I just watched TV, hit the gym, slept.
You can recover/avoid from burnout if people at your job are willing to work with you to change the situation. The big issue is most people in a work relationship are not even capable of changing work patterns. They dont have the management skill to do it, and will have the conversation, but continue down the same path. Thats when you leave.
