Yes, it is hard to hide depression at work. Twice during my life, I have had to take a "time out" -- once from college and once from work. These were separated by almost 40 years.

I don't know if this will help with depression, but it is helping me cope with 10-hour work days. I am wearing a pedometer, and this has made me see that I need more exercise. In fact, a recent article I read says that we should stand for five minutes out of every hour. This doesn't bring fitness, but it does make us healthier.

And of course, exercise stimulates endorphin, the feel-good brain chemical. Tho' I'm not sure if my mini-walk breaks accomplish this.

At any rate, I started walking up stairs more often. At first, I could barely make it up a two flights; now I can walk six flights in an office building (big flights, not like a home) if I have the right shoes.

I've also started taking little five-minute walk breaks. All the smokers go outside for their five-minute ciggie breaks, so I just walk down the stairs (all 6 flights from my office) and walk once around the building.

I've gone from about 2500 steps to routine 4,500-5000 and, as I up the walks around the building, 6000 on a great day.

Even if doesn't cure depression, it will give you something to break up the day and feel proud of doing.

I've lost two pounds, too.
