When I was diagnosed I had to take this very long 500 question test. I'm still unsure about this diagnosis personally. I have an odd personality. I'm not shy, yet I'm very shy. I'm vaguely outgoing, but I also like to be left alone to do my own thing. I don't like to be loneley. I want friends, but I don't. I get up in front of 300 people and be in a play, make a speach, or sing and not feel self-concious.... It's weird.
In my experience, a therapist or psychologist who actually gives you a personality testing is better than one that just sits back and listens to you talk. I would rather have analysis than "and how does that make you feel?" I mean, you need that, too but you also need to know this person was actually trained and has an idea of the differen issues people might have.
