Afraid to make a step

Sometimes I feel so afraid. I'm afraid to try and chase my dreams because I am afraid of failing. If I fail then the one talent I thought I possessed will be gone and I will be nothing. I'm afraid to learn that my mom and my friends were wrong and I'm not worthy. I don't want to expose myself like the no talent people you see auditioning for American Idol who truly believe they can sing. I'm also afraid of the responsibility that comes with success. What if I can't keep it up and fall flat on my face? I am immobilized by fear. I can't move forward and won't go back.
