Hey there,
I, as well am new to this site; and, browsing through I thought I might respond to your issue. I am actually on the other end of your spectrum. I have friends whom can be very obnoxious at times, and frankly, I feel that it is as someone else said in a previous post: you need to closely examine yourself: your needs...and what is most lacking in your life, because these things are probably what are giving your persona this dislike by others. You know, sometimes people just want to fit in and belong so bad that they actually over do it.
