Loner? or just simply weird? or what? u tell me.?

I just cant help it why they like to talk behind people's back when they say they don't like hypocrites? And why... why do ugly people like me, who has birthmarks on face, or just not pretty, will always be a loner? wherever i go,i'll always look down. afraid to look up high cos i hate those ppl who cant accept the people who are ugly or just weird like us. I'm 21 this year. Yet my emotional and thinking, is like a 15 year old kid! haizz....
