So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand.
~ Isaiah 41:10
There is a healthy fear of things which can harm us and proper fear(awe) of God can prosper us.
However, there is unhealthy fear of things which are spun up in our minds. Fear of those things and voices which you give a higher seat than God - will keep you on the floor.
Drawing strength from God's promise is the beginning of overcoming your worry -- and the end to those distracting voices.
