I just don't know...

So I have been struggling with the thought of being a vampyre for a very long time. Honestly the sites I have gone to have given stupid quizzes and unreliable answers. Can anyone tell my the real signs and symptoms of being a vampyre? I keep getting more and more discouraged about finding answers because I just end up with more questions. No I haven't been bitten. No I haven't had someone "change" me. I need some answers, by someone that understands and is much more intelligent in this area than I am.
