Yeah I agree that exercise is not that helpful, the only real benefit for me is listening to happy music while waking may provide a temporary distraction but even that doesn't always work. Even if it does, as soon as I turn the music off then the negative thoughts come back. I find it annoying when people say "you don't look depressed" too, just because someone looks nice or looks happy on the outside doesn't mean they aren't depressed. In fact, it's very common for those with depression to appear happy on the outside.
