Dont understand

I don't get why you people think
liking me is good
people aren't supposed to like me
until I'm 18 than they could
i know that I'm not pretty
don't tell me any lies
the most beautiful part about me
is my boring hazel eyes
I'm not the smartest person
don't have a high I.Q.
i wont say "i believe in god"
because it simply isn't true
I'm not the nicest person
when i want to i am cruel
people think I'm a bully
for the way i dress at school
i am not thin nor chubby
but fluffy inside and out
i talk bad about myself
i leave myself in doubt
i don't have golden skin
not athletic or good at sports
i don't look hot in dresses
i don't look hot in shorts
i have a horrible attitude
i always think I'm right
if i say light is dark
than dark shall become light
you may say its wrong
but to me its what i say
for i will argue with you
through all the night and day
I'm pretty bad at everything
people think I'm lazy
i cant remember anything
my friends all think I'm crazy
i don't have beautiful nails
my hands aren't the best
i will never have straight A's
i don't do good on tests
i just don't understand
why people can like me like that
but when its someone i actually like
i cant get them to like me back
