God can use anyone and many of the people in the Bible were shy and look what God did in their lives. 13 is a hard age and I pray that you will find a group of friends who accept you for who you are. Father God, hear the prayer of this young woman, I lift her to you. May she find her passion in life, for therein lies her purpose. Gift her and bless her abundantly to go out in the world and become a strong woman of faith. AMEN.
