Try digging for the root cause
Your reaction to, and your definition of, stress comes from somewhere. Moreover, the way you feel is not in a vacuum, it's affected by lots of things; the economy, politics, even the weather. Out of your control obviously. Now, onto the things you can control; be mindful of your sensitivities, triggers, habits and beliefs that may bring about stress. Try to be aware of your instinctual responses to certain situations and don't be afraid to work on them.
