Something I have found that may help some of you with your depression is light therapy. I've been thinking for a while that I had SAD (Seasonal Affective Disorder) because I tend to go into hibernation mode in the winter--sleep a lot, eat a lot, do little. So I finally broke down and bought myself a light therapy desk lamp (you can also get the traditional light boxes, or even like hats with the lights in the bills). They're quite popular in Alaska where it stays dark so much, but they can be for anyone. I live in Tennessee, and most people would probably think it's not too cold or dark here, but gosh, I don't think we've had one full day of sunshine since before Christmas, and more days than not are overcast from beginning to end. I mean it constantly looks like rain, day in, day out.
I've noticed that I've perked up some since having it, and am sleeping a bit less. I'm still having motivational difficulties (I keep putting off mopping the kitchen and I can't seem to get the laundry put up and I drag doing a minimal amount of exercise), but I haven't been using it very long yet either, and it can take a couple of weeks to get built up.
Anyways, I thought some of you with depression might want to consider the light therapy to see if it helps a little, especially considering that IBS keeps many people indoors where they get even less sunlight.
