Hi all.

I just have a question, or perhaps a series of questions within a question, regarding BPD.

Is it possible for someone possibly dealing with BPD, who has not been diagnosed with it, to suspect that they may possibly be struggling with BPD?

I have heard professionals say that BPD tends to come along with a lack of insight on symptoms. Is this true for all cases? Is it possible to have some concerns, or suspect that they fit the criteria for BPD?

I may have the complete wrong idea here: all information I have is purely what I have read online.
I actually have several questions regarding BPD, but this is the one I have for now.
