Is this normal for a process of diagnosis?
So, I just went to a particular psychiatrist for the first time today, and my main concern was the possibility of Borderline Personality Disorder. He read a document elaborated by my psychologist explaining all the symptoms I had and my other disorders, and then I told him about all my related symptoms - my unwavering fear of abandonment, extreme actions like self-harm and suicide attemps, instability in relationship and identity, past dissociative episodes, etc. He then said "that's a very clear Borderline case. You're like, classic Borderline." I just felt that maybe it was a bit too fast. Is it normal for psychiatrists to diagnose on the first appointment like this? Is this valid?
