My experience with people who have Borderline Personality Disorder is that they'd rather be diagnosed with just about anything else because they see the BPD diagnosis as delegitimizing their suffering. I've seen people with BPD seek out psychotic disorder diagnoses in order to feel more legitimate. This is the fault of the mental health establishment. The stigma people with BPD endure is pretty severe. Therapists dump them. Hospitals don't treat them with respect. Their social relationships are in a shambles and few clinicians reach out with the kind of mental health treatment needed. The terrible part is people are given diagnoses and medications for disorders they don't have just so the system will treat them better. Taking a medication for an illness you don't have can be life-threatening. The mental health community needs an overhaul on how it treats and diagnoses people with BPD. You shouldn't have to seek out an alternative diagnosis just to get properly treated.
