Why do I have no friends?

I'm overweight, 250lbs, I don't wear make-up, I don't really do much with my hair (except dye it crazy colors), I have glasses, and I have my own sense of style. I'm shy because I'm fat, and I'm fat because I'm shy, it takes someone coming up to me and asking me things, for me to open up and show my true personality... People have just always hated me, my whole life... even before I was fat... I was chubby in Kindergarten and someone called me fat, and ugly and I was a very active little girl... but my father would give me adult sized portions, and not let me leave the table until my plate was clear... as he did that I became less social because I didn't have anyone to play with... and became overweight.

So why do people just instantly not like someone? What is wrong with me...
