Mania is associated with bipolar type I. If I was bipolar it would be type II. People with type II experience hypomania. Narcissist also experience hypomania. I know for a fact I'm not bipolar though lol.
What separates me from an actual bipolar person is that even when I'm depressed I still feel like a god or king. Bipolar people usually lose that high self esteem once they get depressed. Aside from that, I created the whole bipolar thing as a means for attention lol. People will believe just about anything if you say it the right way.
You have to make them believe by believing it yourselves. Since I actually thought I was bipolar, so did everyone else. I'm definitely a narcissist though. Basically my dad was showered with love and affection as a child too much. So he had a sense of an entitlement at all time which got worse and worse the older he got.
When he had me though it was the opposite. He never gave me the love and attention I required as a child. Basically I developed narcissistic personality but I was more of a covert narcissist (read about them here: http://www1.appstate.edu/~hillrw/Narcissism/shycovertnarcissist.html). Eventually I started learning more about narcissistic personality disorder and my shyness dissipated making me become more of an overt narcissist (read about them here: http://www1.appstate.edu/~hillrw/Narcissism/arrogantnarcissist.html).
To conclude, I don't have bipolar disorder and never did. Also I'm actually a overt narcissist but just didn't know it. Which means I have to completely change my argument and tell how overt narcissist are better than covert narcissist making me some what of a hypocrite, but at least I'm an honest hypocrite.
