My best coping mechanism regarding emotions is simply to dismiss the thoughts that elicit the emotions, and look right at the emotions themselves. When I cut off the power supply, the emotions begin to dissolve immediately. If the triggering thought or circumstance is strong enough, I might have to do this several times because it soon returns, but with practice this technique really does help me. Also, when I do this repeatedly, I begin to realize that the thought, which triggers the emotion, is secondary to my mind's attachment to the emotion. I don't have to look far to find another trigger if I'm in that frame of mind.
