 How do you exhaust an emotion? You exhaust an emotion by staying in it too long. All emotions have a shelf life. Emotions are like tunnels. They have a beginning, and they have a middle, and they have an end. When you get stuck in the middle of an emotion and stay there too long, like staying in fear, or anxiety, or staying in anger, or upset, or staying in worry, or despair, or heartache, when you stay in an emotion too long, it's like you get trapped inside a tunnel, and you don't come out through the end in the speed with which we should do that. And there's all kinds of reasons why we park up in an emotion, but that's how you exhaust an emotion. And this is especially prone to happen if you are an over-thinker like me.
