And I'm going to add to that that my first experience with feeling good came a couple of weeks after I started with Prozac. I was walking around a shopping center with my husband, and all of a sudden I realized, "Something's wrong!" What was wrong was that for once I was not depressed. I never knew how it felt before. And once I started analyzing how Prozac worked I realized that for some reason it had started to block the negative thoughts that were constantly in my brain, beating me down, telling me I was worthless.

It used to be that I would have i or 2 lucid seconds after I woke up in the morning, before the downward spiral of thoughts began, where I would feel OK. Then once the self-hating,
self-critical thoughts kicked in I was a goner for the rest of the day. Wonder if that might be a factor for you.

And no question -- sometimes exercise can help. Gets you focussing on something other than the negative thoughts.
