Have you just observed your "mood" without any desire that it should be one way or another, good or bad? You know it cannot last very long. Different chemicals are released in the body and we label these things with words like sad, afraid, anxious, good mood, bad mood. None of it is permanent, though. It is an ever moving stream.
The "mood" has long passed, yet you are still thinking of it. I wonder about this.
“So long as we believe in our heart of hearts that our capacity is limited and we grow anxious and unhappy, we are lacking in faith. One who truly trusts in God has no right to be anxious about anything.”
― Paramahansa Yogananda
