I get something very similar. I'm hoping that not being the only one will be some small consolation, because I'm not sure what to do about it either.
Sometimes I can make myself work while watching trashy television - I mute the ads and get a couple of minutes worth done, then turn the sound back up and watch something mindless for 5 mins, and so on. It's much slower than when I'm motivated, and it eventually drives me crazy, but it's the only way I know how to even start. If I get rid of all distractions and just sit down at my desk and try to work, nothing happens - I just end up stimming til I meltdown.
