From my experience, people with schizotypal PD don't even really care that they have schizotypal PD. Most tend to be emotionless, withdrawn from friends and family, enjoy their time alone, and have odd beliefs (like you said) that sometimes have to do with God. They can think a major event in the world had something to do with them, and don't find much humor in anything.

I just did Schizotypal PD in my Abnormal Psych class (I wish I had my book on me right now...).

If you have these symptoms, then maybe you should get it checked out (if you're still questioning your diagnosis). Good luck!
