Anxiety in a man's heart weighs him down, but a good word makes him glad.
Proverbs 12:25

Cast all your anxiety on him because he cares for you.
1 Peter 5:7

Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Philippians 4:6-7
