Touching rock bottom, rids you of fear because there is no further you can go without dying and there is nothing more to lose. You have to let go of everything you think you know. The certainty of your life is departed. You are naked and on your knees before the world. You think it is the end. You spend days resisting the suffocation of your own annihilation only to discover that when you accept the failure and defeat and welcome your own annihilation, you are suddenly in the light. You are suddenly breathing air.
