A lot of BPD's have not officially been diagnosed for a lot of various reasons. Some doctors are hesitant to due to people's health insurance and other concerns, some have an extremely low opinion of BPD-look at it as being incurable-and don't want to brand people with that stigma, and some just don't know BPD well enough to make the diagnosis. One thing about psychology/psychiatry is that so many seem to forget is that it is an inexact science and psychologists are imperfect people. All diagnoses are based on observation and different people are going see different things. I've seen so. so many misdiagnosed it's not funny. I'm not telling people that the doctors can't help and that you shouldn't trust their diagnosis and treatment plans, but we are the only ones who are truly in our heads and it's okay to question what we're told and not blindly follow whatever we're told. In my opinion, if you feel like you know yourself and you've done the research and BPD seems right to you, then go with it until your body or head tell you otherwise. Okay...I'm off the soapbox now. You are welcome here.
