Sorry i'm not her

Sorry I'm just in so much pain
it's driving me insane
but i know you don't care at all
you never see me even when i fall

i know i don't matter
sorry I'm not her
you can just leave me here
eventually I'll disappear

so what's the point of f**ken around
either way
I'm slammed to the ground
so what do i do
i can't just run from you
