A tough one. The one time I remember having a problem like this, I wasn't exactly tasked with doing programming at work. So I solved my problem by turning to hacking! I did nothing but Perl for weeks. A rather productive time of my life, actually. Fortunately my boss was very pleased with all the code I wrote. Try this: Change your work environment. Move to a different office. Work at the library or the coffeeshop. This is normally not a good thing for your productivity -- what you generally want to do is establish productive habits, and encourage them by keeping your environment consistent and allowing it to cue those habits. But being surrounded by familiar things might be distracting at a time when they tend to dredge up feelings of unhappiness. There was a time when simply walking down a particular street would fill me with dread. Emotions are cued to places. Fortunately I'm much better now. This may be why we're always telling people who are feeling burnt out to take a vacation and travel somewhere.
