Allana,
Why don’t you make an appointment to have a face to face confession with your priest? It would be more like just sitting down with him and having a conversation. He can walk you through it. You don’t have to know all of the right things to do or say. Just speak from your heart just like you do to God. It’s OK to cry and be emotional too. I will tell you what, every priest I have ever talked to at confession, has been so kind and so understanding, their voice so soothing and healing. Don’t let anxiety rob you of this wonderful sacrament. If you need to ask someone you trust to call and make the appointment for you. Ask them to walk you in. Whatever it takes to make you comfortable. Once you go, you’ll wonder why you ever waited.
