I was mad and upset the other day.
I searched for a guided mindfulness exercise that might calm me.
I found what I needed at the University of VT.
When done with the exercise, I did another one.
When done with that one I had the thoughts, "they are feelings, they will change. Do not feed them, you will be okay."
It took awhile, but It changed.
I felt an emotional hangover, but I was okay.
