Analysis of Miserable me

Sitting on the bathroom floor
holding my heart tight
while the tears burst out
from my black pupil eyes,

i have turned my self
into a monster, I think
i have thoughts in my mind
may be i can't let them sink

I know am different
I don't fit in
but am trying so hard
so let me in

Let me in this world
as blood oozes from corners
of my viens that I slit
to grieve for my self
crawling my skin Little bit.

how do I say that
there's a monster in my head
that makes me shivery
I don't belong here
am taking me away with it.
