Self harm/Self hate

It sucks when you feel like this
and you have nowhere to turn
no friends that you can call on
its a lesson I have to learn

still struggling with this heartbreak
i am battling everyday
but when your stuck in your head
sometimes there is no other way

we all have ways of coping
and not everyone's way is right
but it's what helps you through
Its what helps you to fight

but all my fight has gone
you took away my heart
it's in a million pieces
And I don't know where to start

So as I sit here crying 
trying not to harm 
surely just 1 wont hurt
one little cut to my arm.
