Meditation helped me get more in tune with my emotions. Simply learning to recognize and acknowledge my emotional state has helped me understand the cause/effect dynamics of my emotions.
One thing i realized was that most of my negative emotions were self induced, the result of stressful ruminations. There is no upside to such ruminations. Conveniently, meditating with the intent to acknowledge but not pursue or otherwise react to thoughts is a good way to learn to get out of circular, stressful ruminations.
When your own actions don't cause you stress, it becomes easier to explore and take risks and seek out what causes you positive emotions.
YMMV but meditation taught me to better manage my peace of mind.
Edit: And exercise more. Its a good way to make you feel alive.
