Shotgun, I don't know where you live, but I can tell you the single most effective thing I can do for being depressed is to force myself into some sneakers and out the door for a walk. Some days it really is force. Once I've done it, I have never regretted it - but there have been plenty of times I've regretted NOT going.
It doesn't have to be long, either. Just being outside, moving, and looking around really helps stabilize the chemicals in the brain. You will find your mood picking up, you'll do some problem-solving while you're out, and your energy will increase.
I really know what I'm talking about on this one. Do it for your kids, if you don't want to do it for yourself. They deserve an engaged parent, not one barely making it through the day. It's hard work getting up the motivation to beat off the blues, but not so hard to manage once you get moving. I wish I'd known this even last year. Things would be so different if I had.
