Indulgent emotions

Hi there! I’m wondering if the emotions we label as “indulgent emotions” (confusion, overwhelm, doubt, worry, etc). are ALWAYS indulgent. When we call them indulgent emotions, to me that has the connotation that that is what they are, always and forever, each and every time we feel them. Is that how I’m meant to see them? And can any emotion be indulgent if it’s not useful and is being used to avoid another emotion (fear, rejection, etc)? Thanks 🙂
