Possible New Diagnosis???

So I had a week's hospital stay at the public psych ward. I have no memory of the first 3 days, so I got a copy of the letter and info that was sent to my GP.

Apparently in the ED I was agitated and rude. Then when I was moved to the psych ward I had an assessment. Here they wrote. Impression on admission : cluster B traits (BPD traits) evident throughout admission. WTF.

I have Major Depression and Anxiety and they think I still have PTSD. But now they want to add Borderline Personality to the list.

They never mentioned any of this to me. At all.

So what am i meant to do with this new diagnosis? And how would I even know if it applies to me?
