Understanding the underlying message of jealousy

All emotions (happiness, sadness, fear, etc.) have an underlying message to us. These messages might not always align with reality. For example, fear tells us that we are in danger, but just because we feel afraid, doesn't mean we are actually in danger.
Jealousy as an emotion tells us that we are losing or going to lose something to someone else. A way to manage this emotion is to check whether that is actually true!
