If you've never confessed, it's impossibly hard. The strange thing about confession is that when you have a loving and supportive ear, you'll wonder why you waited so long. Like anything, you get better when you practice and oddly enough you may even find you could start needing to less as time goes on. Push through that awkward times in the middle and know that Jesus is listening.
James 5:16 Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective.
