Unfortunately right now I'm the target of BPD rage from a coworker/client. This particular person meets all of the DSM tier 5 qualifications plus all of the physical symptoms with their heart and everything else. I suggested to them but they could possibly have BPD. Needless to say they did not take that suggestion very well. Even though this person got me fired, I genuinely care about their well-being. What's the best way to convince a BPD sufferer that they have BPD?
