I'm curious how much exercise you do newgal, and how vigorous it is. I walk my dog 3-5 miles a day and while it sometimes helps me feel a bit better, that's usually because it's the only time I leave the house (he bugs the shell out of me and destroys everything if I don't walk him consistently). But it doesn't really change how depressed I feel. I used to hit the gym 4 days a week for about an hour each day, doing both cardio and weight training, and that certainly didn't prevent me from falling back into a depressed hellhole. It made me feel a little better for a short time, and that's it. It seems like I have to exercise pretty intensively in order to feel any effects, and like others have said, I just don't feel like I have the energy to push myself that hard.
