To me it means bearing my soul before the Lord my God in prayer. God know all our sins. He wants us to confess them before him and he will give us peace. He wants us to give him all of our burdens. Once you give it to the Lord he will help you work through what ever is holding you back.
Proverbs 3 5-6 Trust in the Lord with all your heart, and lean not unto your own understanding. In all your ways, acknowledge him, and he will direct your path.
