Hello sisterstruggle. I understand the situation you're in. I agree with the others who have posted already - avoid contact with your sister if you need to. There isn't anything you can do now. It's all up to her. There's no need for you to experience all of her drama for the next 10 years or however long it is. I've been doing it at least that long, and I wish I had stopped years ago. It's a nightmare. I'm sorry you're having to deal with this, but this site is a good place to read and learn about addiction.
