Dear doremi:
You are afraid to fail. Unfortunately, none of us humans can live fear-free. Unfortunately it is not possible. You have to find a way to live with fear, to endure it, to manage it, to plan your actions so that you minimize the risks of failing and maximize the chances of success. You can’t guarantee success therefore there will always be fear.
When you are afraid, you bring yourself back to a state of calm. From that state you plan. From that state you act. Over and over again. Fear is something that you will never be rid of, forever rid of. Not going to happen, so you live the best you can with it. You view options, figure out the statistical chances (not necessariy exact calculations) of success and failure of taking this option and taking that option.
