sometimes if you can find an affirmation that lifts you up and away from fear, say it a few times and it will help.
one I used years ago is ” I am part of the universal design, I am loved by life itself”
and  this part of a Broadway show, The king and I?  ” When ever I feel afraid, I hold my head erect, and whistle a happy tune, so no one will suspect I’m afraid”
.my new one, because my ex was trying to put me down, say it loud!  “I  am  a   bright  shining  star !”
all gives confidence to me.. find yours.. good luck!
