Therapist and psychologist are reluctant to diagnose personality disorders or schizophrenia because these are lifelong labels. They have to establish an enduring pattern for a personality disorder. They leave it to a psychiatrist to do or a PHD with a test. My PHD that diagnosed me schizoid tried to make it clear that I was not schizophrenic to which I pointed out it didn't matter because that is how I am treated anyway. He had such a dumbfounded look on his face. You're better off with out the lifelong label just concentrate on the treatment.
