590 calories. . . is that all?

I'm sitting here eating an sausage egg mcmuffin and I think to myself "How many calories is this" Well to answer my own question . . . the McMuffin and the hashbrown was 590 calories, with 36 grams of fat. I just sat there and thought "it's really amazing that I'm not morbidly obese" I go through this phase every so often where I am just disgusted with the way I am. I don't really know how to explain it. I just am fed up with myself. I sit here at work on my ass for 8 hours everyday. Then when I get home, what do i do? I sit on my ass and watch TV. It bothers me, but I don't have anything better to do. I need a hobby
