Well I am not even on all that much medication and I feel the exact same way. Lost I could stare at a tv show even one that I love and end up thinking huh!! Then I stare at the mounds of ungraded student work and I want to faint... It like hundreds of pages that I have to read and mark, and I hate feeling of being lazy or devoid of want, but I look at it and think what am I even doing.

However, I did find one thing that makes me happy some low calorie soda with real sugar and limes that tastes almost like a beer with lime which makes me some what happier when drinking 1 or 2 of them.

For you maybe watching your alien movie and start writing about them a bit might help you get out of your writing rut or go shopping for something new and fantastic to try and eat.
