When you can't sleep pick up the bible and start reading it, go to the Psalms or Proverbs where you can learn much wisdom and how ti leave your friends and problems to the Lord.
Lord help this person learn there is peace in you and comfort in our times of trouble. I pray in the mighty name of Jesus Christ, amen.
Psalm 37:4
Delight thyself also in the LORD; and he shall give thee the desires of thine heart.
