i'm dying from the inside out

some die from the outside in
like by a car
or a train
but this is like caner
like cancer in my brain

silent until deadly, until silent once again
killing me slowly, trapped in my body
living within me
waiting me out, i'll be dead by first light

so on my tombstone
please don't write:
died by car or train

write:

died in vain
died by strain
died from me, killed by me
slain by my own brain
murdered by my own body
set free, freed solely by me

she died from the inside out, can't you see?
