You could then take the action you need to effectively handle your situation. The moment you let go, everything seems to change. With the fear and upset gone, you become creative and able to discover solutions that you could never have seen before. You become naturally effective. To see this another way, let's look at the nature of fear.
Fear is created by the avoiding and resisting of some future possible event.
For example, let's say that you are resisting the possible loss of your relationship. The more you resist this loss, the greater your fear. As your fear increases, so does the chance of your fear coming true. The greater your fear, the more you become threatened and the more you hang on. Then in turn pushes the person further and further away.
