How do people do it without swimming?

I've had a mildly rough week. NO one is dying, or very ill, or anything at all like that, but it's just been a slog to get through. And I consistently turn to the pool to get in and beat all of my frustration and tiredness out. I just don't know how normal folk do it without swimming :)
