Zombiefied

I'm dying on the outside, but i will still go on with my day,
Even if it's getting worse in everyway,
My limbs are shrinking,
Because I'm not drinking,
My heart is begining to plumet,
Right down to my stomach,
My hair is falling out,
It's making me want to shout,
My brain's coming out of my ear,
and it's getting harder to hear,
I can't use my nose,
And I would like to smell this rose,
Next is my arm,
Watch out, it might cause harm,
And now I can't see,
Ahhhhh what's happening to me?
