1. If you see a person showing symptoms of personality disorder, encourage them to seek help. They will get defensive, do not argue with them. Express your feelings and concerns instead.
2. When you share something that might potentially harm you, remember that reactions such as shock, anger and fear come out of concern for you.
3. Keep your attention focused entirely on what is truly your own concern, and be clear that what belongs to others is their business and none of yours
4. I think that you should not concern yourself with this because it honestly do not concern you.
