I have family yes, but strained (in differnet ways with differnet members) relationships with them and I have no firends really... well the one or two I did have I lost through getting drunk which for me eqautes being violent and obnoxious.
YOu go to nottingham right? I know tons who wnet there from my school (about 12 I think) and they are all differenet types, so Im nots ure how they could say "he cnat go to this uni". Although I do feel a little out of place at where I am studying given that I feel (what with my grades and attitude) I should be at a higher uni.
And yeah some people have natural charisma, and some seem to almost have negative charisma. I wouldnt dwell on it to much I too have given up on society many a time, I used to find escapist pleasures through such things as videogames, the internet and general studying.
YOu cant change peoples first impressions, all you can do is demonstrate through your actions that you are not who they make you out to be.
