Well, the difficulty separating paranoia from reality could be a symptom, certainly, also worrying about your neighbors reading your mind. What does your therapist have to say about these things?
"If you think you're crazy, then you're not," so your therapist tells you. Yeah, I've heard that in many many places. I don't think it's used properly very often, really. I mean, I think I'm a paranoid schizophrenic, does that little adage mean I'm not? Apparently not, because according to the doctors I do indeed have paranoid schizophrenia.
Really, I knew a psychiatrist 30 years ago who had a sign in his office that said "Just because you're paranoid doesn't mean they're not out to get you."
Have to ask, how's your relationship with your therapist? If you are telling your therapist you're having problems distinguishing reality and you think people are reading your mind, I rather think you should be getting more back than "If you think you're crazy,then you're not." Seems pretty lacking, but maybe that's just me? I dunno.
