Forgive yourself, for anything and everything. This includes things you did as an adult and way back to things you have done since you were born. You can't change the past, so let it go and move on. You won't really have peace in general until you make peace with yourself. You need to generally like yourself and get along with yourself, because you will always be there. You can't get away from yourself. Wherever you go, there you are. :) So become your own friend, then you will have peace inside of yourself. God, the perfect and holy one, even gives you grace; so give yourself grace. You never have been and never will be perfect. So get over trying to be. Amen
