Do not be ashamed of the scars that life has given you. A scar means the hurt is over, the wound is closed, you endured the pain and God has healed you.
He heals the wounds of every shattered heart. Psalm 147:3 (TPT)
But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed. Isaiah 53:5 (NIV)
