It's when I don't exercise that I feel worst. So when I exercise on days I don't really want to, doing 30 - 40 min on my ancient stationary bike, I feel better just from the accomplishment.
The days I go to yoga class are even better. I can feel horrible going in but I almost always feel good when I leave. I take a class for beginners or people with any health challenges so it's pretty gentle and I sometimes feel like I've had a massage after class. We have a new Ivengar teacher who teaches half the time now and she gave me a copy of a bunch of exercises for ulcerative colitis from some big book Ivengar teachers use. It's pretty cool and I've been trying to do a few of them every day, too.
Try whatever exercise you can just for that sense of accomplishment. It does feel great, doesn't it?
