Memorizing Scripture is so important, especially in times of weariness. These are my go-to verses for times like these:
Matthew 11:28
"Come to me all you who are weary and burdened and I will give you rest."
Proverbs 3:5
"Trust in the Lord with all your heart and lean not on your own understanding."
Philippians 4:13
"I can do everything through Him who gives me strength."
1 Peter 5:7
"Cast all your anxiety on him because he cares for you."
