Big feelings

If inside I am boiling, but I need to avoid boiling over for the sake of goodness, what's the best path forward in the moment? Afterward?

Over time would an over- or under-attentiveness to emotions become an addiction and thought pattern of its own?

God, please help me to acknowledge the truth of emotions that point in the direction of your larger and greater truth. Deliver me from becoming addicted to the highs and/or lows of intense emotions, that I might rest in the greater truth in between. Show me when it's time to express and when it's time to practice restraint. Come Holy Spirit!
