Recycling your emotions is no bueno
You're better off offering them a cup of tea.
Have you ever met someone who you'd describe as "bitter" or "anxious"? Those people have been recycling their emotions.
When you recycle emotions, they harden. Anger recycled turns into bitterness. Fear recycled turns into anxiety. Gratefulness recycled turns into happiness.
When you don't let your brain process an emotion fully, when you run from it, it stays in the back of your mind. When you don't accept and acknowledge and give space to the fear or anger you feel, it festers.
The more you run from acknowledging your fears, the more you recycle those negative emotions. The more you recycle them, the more they become a part of who you are, instead of just a thing you occasionally experience.
Next time your anger or fear arises, acknowledge it explicitly. Welcome it as a natural part of being alive. I literally imagine opening a door and saying "Welcome" to the dark feeling and offering it a cup of tea. I tell this emotion that it's okay for it to exist.
Try it :) You'll find that this terrible emotion that you don't want to experience just fades away. Once it's welcomed, once you stop resisting it, your nervous system calms down and you will feel peace.
Emotions last at most 90 seconds. By acknowledging your fear, you're able to control it. Awareness brings control.
When you stop running and avoiding your negative emotions, then you stop recycling them.
