Giving up hurts the most

You think you know me,
you have no idea what my mind contains,
all the hurts all the pains,
i cant take it anymore,
stay away from me,
soom you will see,
all the fears and tears you have brought me,
i lie awake thinking of you,
knowing you will never be mine,
i see you with her,
kissing her,
loving her,
it eats at me,
wondering, thinking, why it isnt me,
why cant i be the one,
the one you love,
it seems no matter what i do,
all i can see is you,
i look all around and all i can focus on is you,
for in you i find me,
its inevitable,
its true,
and because of your actions,
my heart will die,
and you will see me cry,
this is my last goodbye
