You don't

It's hard to understand
It's hard to explain
That you don't know
How much I'm in pain

At night I cry
My heart is bleeding inside
This hurts so much
I wanna die

You don't know
and you don't care
That this is killing me
It's so unfair

You don't notice the pain
Or the scars on my arm
and you're not there
To take me away from harm

You don't hear me screaming
You don't see me crying
I don't think you'd care
If you saw me dying
