Unburden your soul by going to confession with a trusted, knowledgeable and loving priest. Keep close to the truth that the recitation of sins in front of Christ with a properly ordained priest will prepare your mind, body and spirit to receive God in deeper and more lasting ways.
While we can and should speak with God in a familiar sense or pray our humble prayers to him, the act of going to a confession helps us to be repentant. This is important because God loves a contrite heart. If you can do this on a regular basis, you will make way for deeper prayer in meditation, which can lead to God's greater presence in prayer, which is contemplation. Ultimately, these lead you on the path to theosis, which is union with God.
So, go to confession.
