Fear is paralyzing and I need to keep on moving.

Courage almost never means the fear has left the building. Ask anyone who does frightening things for a living and the description is the same: the hands go afterwards, not during. Fear was fully present the whole time and the work happened anyway.

Which changes the assignment. You are not waiting to stop being afraid before you move, because that appointment may never be kept. You are looking for the smallest action fear cannot actually prevent — the email sent, the number dialled, the single step that happens while the entire system is still shouting.
