I'm wondering if some BPD people can come across as arrogant. I ask because of an ex online friend I used to have. She had a lot of BPD symptoms but she also had (and still has) a tendency to brag about her accomplishments and give the impression that she was "all that" although from what I could gather she was very insecure and actually had low self esteem. In the end I ended the friendship, something I still feel a bit guilty about at times, because I could not cope with the constant devaluation and manipulation from her especially as I have emotional problems of my own. She was not receiving any counselling saying that she once had a counsellor but he/she "did not understand" her! I'm still trying to make sense of all that happened even though we are not friends anymore. My own counsellor suggested she probably had BPD but from my research bragging and arrogance are more of a symptom of narcissistic personality disorder (NPD) than BPD. I know only a qualified psychiatrist could diagnose her but I was wondering if bragging and seeming arrogance can be a symptom of untreated BPD.
. Personally I suspect my exfriend has spiritual issues which I won't go into here but, like you said, that's none of my concern. I'm sorry to hear about the person close to you but in the end all we can do is pray for these people and leave them in the hands of the Lord.
