I'm with TishaBuv on this one - yup, self awareness completely possible. I myself was well aware of my traits....and clueless about it being BPD. 2nd question - lack of self awareness can be true, if the person with BPD is also a narcissist, for example, but absolutely not true for ALL cases. 3rd question - yup, very possible to have concerns or suspicions you might have BPD - but only a trained pro can tell you....and keep in mind, they may not tell you. Some aren't specifically trained in BPD, and so don't know to diagnose your symptoms as such. Some are trained, or aware of it, at least, but won't actually give the diagnosis, due to past stigma associated with BPD. (those are getting more rare, with more study and understanding of the condition.) And then there are the ones who are aware of it, trained in it, and can help you with it. Good luck in your exploration.
