Sister, confess ur sins to a priest. He will obsolve u from ur sins.
Read Leviticus 16:30, For on that day shall the priest make an atonement for you, to cleanse you, that ye may be clean from all your sins before the LORD.
It's scriptural and u feel so renewed and refreshed from ur sins afterwards. Trust me i go to confession at least once a month. When u go to the confessional and the priest says i obsolve u from ur sins, those sins are plunged into the abyss of God's mercy. Where there is a sign..NO FISHING. no more need to search for past sins, for they are no more and forgotten =)
