I say that they way you act online is far different than you do in reality. Through the times you speak deeply I can tell that you seem to be sometimes self conscious and may have some ammount of self doubt. You come to the internet because it is a place where you can express yourself to people who have not met you in reality and who will not prejudge you for whatever reason, or you come here to try to be the person who you want to be as you may dislike who you are or who society or people around you have forced you to be. Your mind seems to be a chaotic place, filled with thoughts that would take a lot of musing over to be truly coherent yet at times you find yourself empty, with no ideas about what to say.
When I come to think about it you seem to be a lot like me, although still with your differences like all people have. The problem with this post is that only you can truly say what kind of person you are and even if you try it is often tainted as it is a one sided veiw.
