Breakthrough #1:  Emotion is not  intentional.  This is an idea that I have been aware of for a ling period of time, the idea that emotions are not chosen or selected, but that they demand to be felt.  Emotions are an extremely needy bunch, always craving your attention and clawing for space inside not only your head but also your heart.  Jealousy is one that often claws his way out quite viciously.  Whether conscious or not, he whispers in your ear, coercing you to act in ways you never thought yourself capable of, to harm those you love whether you believe you desire to see them in pain or not.  He buries himself deep within the burrows of your soul, hidden under the layered sediment that is other, lighter emotion.  When you least expect it, he can swell up inside you and roar like the tides, waves of him crashing down and devastating everything in their path.  And after the waters have cleared, what is left of the once balmy sea is left with regret, self hatred, insecurity, guilt, and loneliness.
