Introverted or Anti-Social?

Is there really such a thing as introversion or exttroversion?  According to the famous Myers-Briggs inventory, I would be an introvert.

When there are tons of people around, noise from the TV or other peripheral noise, I tend to start feelling very tired.  It sucks the energy out of me.  I watched a young lady on a TED talks video give a convincing argument that some people are just wired to live quietly.  Introverts take longer to process information because they are just wired to do it that way.  

But I hesitate to use the pronoun "we", as in "we like to sit in the corner of the room at parties and observe."  Because, just maybe I"m really antisocial.  There's nothing introverted about it, I'm a snob.  I'm critical and I like to make fun of people.  This is sounding quite schizophrenic.

Was Jesus antisocial when He wandered off by Himself to pray, when the disciples finally noticed He wasn't around and went off looking for HIm??  Was He just tired when they found Him in the bottom of the boat sleeping, even though everyone else was on deck, fearful of the storm?

However we lable it, we know for certain that Jesus always did what was right, so there is hope for me that I'm doing ok if I need to just be away from people for a time.  Likewise, if I'm being an unfriendly jerk, then I know that is not  pleasing to Jesus and I should really check my attitude and not make excuses for it.
