Yes you are right. My mood and self esteem are my primary concern. Here in my country psychologists diagnose personality disorders and together with psychiatrists they diagnose bipolar disorder or other psychiatric diseases.
What is PI? And BPD? Afaik BPD is borderline personality disorder but you might mean bipolar disorder?

Yes ditch all the labels. But this narcissist diagnose was while i was hospitalized and as a result they refused everything i asked for and they didnt let me talk with copatients alone. Everytime I talked to someone and we sat down somewhere, soon a staffmember came to intervene. As if i abuse or harm others. And even if i would be a narcissist, is that the right way to "cure" it, frustrating someone? That really made me paranoid. I got a one flew over the cuckoos nest feeling there. It traumatized me in a way. I was there 7 weeks. Worst experience in my life and it didnt help at all.
