"Can I have some suggestions on how to walk through fear."
Don't walk through it. Eliminate it. Fear comes from the delusion we're under threat. We're not. We're spirit. Our material lives can be threatened; we cannot. If we are identified with our material lives, we will be afraid. That is what self-reliance means, and that is the root of fear (page 68 of the Big Book).
Challenge your delusions instead. As my sponsor says: f*** fear.
We get to choose to be victims of our delusional thinking or servants of God, aware of our permanent safety when we remember who and what we are, simply playing roles in this earthly realm.
