You're not alone. I feel the same way but in reverse. I wake up, go to work, and usually find a reason to stay there until almost its almost dark. After that I leave work and go straight to the gym. I try to keep myself as busy as possible because when I get home I know my depression is only going to kick into high gear. Crazy part is the people at my job think I'm super dedicated and the hardest worker there - they have no clue why I log the hours I do -- its b/c the only thing waiting for me outside of work is an empty place. So maybe coming up w/ a routine that keeps you really busy would help a little. Its not a cure, but it may help.
