Me an people

What i don't understand is

i know I'm not normal,
i know I'm sad
i see every one around me,
they never see what Ive had,

their so blind,
it makes me mad
they always judge me,
and the result is always bad

they avoid me
and i in turn,
i feel so lonely
sometimes my eyes burn

i don't know why
I'm outcast,
its not like
i tell them my past,

i know if i did
id get pity,
but i don't want it.
it would be empty

they don't know me
and they never did,
wherever Ive gone
it's my past i hid

what i don't get
is why its always the same,
it doesn't matter what i do
my life is filled with shame

i know its not fair,
but then, what is?

Ive never done
anything to them,
but now my trust is
like a torn hem,
all ragged and
never to be worn
again
