I’ve been in mental health services my whole life and just recently got out of hospital after a suicide attempt and had one appointment with a psychiatrist and now I’ve been sent a letter telling me I’m diagnosed with eupd?? Is this something you can just be diagnosed with without someone seeing you multiple times and without even explaining what the disorder is?

I read through the criteria and it literally does not sound like me one bit and there was no questions along the lines of the diagnostic criteria in my appointment with this psychiatrist
