Cathy, You only have control of your own actions. You made amends, that is your part. The other person decides to accept or forgive, that is their part. Even if, you didn't have a drinking problem. Not everyone is going to forgive you. There are somethings we have to accept. However, you don't have to listen to hurtful thing from your sister or anyone else. Just simply say you are no longer that person, and I can only control future behavior. Sometimes, amends did get excepted for a long time.
Remember, we have to earn peoples respect and trust. Don W
