I never experienced a real burn out, but have been on the way to it a few times. From experience I know that when all seems to become too much, I need to take a step back. In the end I do realise that some pressure can be good, but too much of it can be devastating. This also counts for pressure we put onto ourselves. I would advise to not force yourself to write yet another great article, but leave writing to others when nothing comes out of you. I think you shall drop being to critical towards your work; Post whatever you feel like. In case some autovoters dont like it; They can do something about that. Don't be to harsh on yourself. Easy to say, I know. But it is the way to go; Removing your inner pressure is the first step, I think...at least that was always the case with me when I got in overload situations. You can do it! :)
