The past is the past. We are to live for each day anew. What is the problem with your sister, your family period? God forgives us all. No one is to judge another person. He forgave the adulterous women and told her to sin no more. I'm sure your other family members have things in their past they don't want told. You should hold your head high. The others need to learn they are to form their own way of thinking and not listen to others. Everyone should sweep around their own front doors before they sweep around others. Keep a smile on your face and be thankful for each day.
