To put it bluntly

It only hurts when I breathe

And I only breathe when it's necessary

So it doesn't hurt that bad

I only bleed

When I cut

It only stings

When it doesn't

You only talk

When I listen

You're only angry

When I scream

I only scream

When I want to

You only beat me

When I'm bad

I'm only wasted

When I drink

I only drink

For the pain you never had.
