Maybe what you share with others is reinforced within yourself. Can you do an emotional reset by sharing a bunch of positive stuff with other people?
It makes sense. I shared with my wife that I was feeling at peace in our relationship. She was happy to hear it and went on to explain how she was feeling about us. Hearing her satisfaction felt great, which added some depth to the inner peace I was feeling.
Maybe emotional health is all about establishing positive emotional feedback loops with other people.
God knows negative emotional loops are common. Many of us form our very existence around them.
When you feel a positive emotion, share it!
