Fear can teach you, prepare you, heighten your senses, motivate you, and compel you to take action. Or it can bring you to a standstill.
Fear is a powerful influence.
Whether that influence is useful or destructive is up to you. Your fear is a strong message to you, a message imploring you to do something. It is telling you to take action, to focus your efforts, to make a positive difference. It is reminding you that you're capable of all that and more. Your fear is preparing you to turn a difficult situation into a great opportunity for growth and improvement.
