Pray these three words out loud to God.
“I love you.”
If you don’t feel like it is true, ask God to show you why. Talk with God about this.
One other suggestion: Try praying John 3:16 and personalize it. Put your name in for “the world.
This is how much God loved the world: enough to give his only son, so that everyone who believes in him should not be lost but should share in the life of God’s new age.
