I have read so much about PERSONALITY DISORDERS that I should become a shrink. So can someone please tell me how a person with NPD get diagnosed with BPD instead?
No one on the internet can tell you how or diagnose you. If they claim they can, they are probably not reliable.
For those conditions you need to speak with a GP, get referred to a Psychiatrist or a psychologist who could discuss it with the individual and make a diagnoses from their findings.
