Yes, I have felt that way, without being suicidal. It's an intellectual/theoretical proposition. However, it is false because it's only in our head...an example of the faulty thinking that people with BPD have. Recognize it for what it is, and then dismiss it as "one of those weird thoughts I have because I have BPD" and then you can move on to reality. Remember, you don't know what other people are thinking about you unless they tell you, explicitly, and even then, you have to take it with a grain of salt!
