Eat healthy and try to take your vitamins: This sounds a little corny, but you'd be surprised at how much effect physical health could have on your mood/emotions.
Regular/routine exercising: For some reason when your body gets routine exercise, since your body is connected to your mind, it's as if you go through some Jedi mind tricks on yourself and your feelings of being down over time fades away...but the key is over time.
Network of support: But the best medicine of all is having support from family and true friends. Even if your troubles are not being discussed, as long as you're around them and spending time with them, the positive effects last a life time. While you're at it, laughter with loved ones is a plus!
