You don’t understand depression..

So you wanna know what it’s like to have depression?
It’s like trying to breathe with a heart , that’s in need of compression. 
The walls are closing in, and I don’t know how to survive. 
It’s like trying to swim, but you’re hands and feet are tied. 
I tell you about my pain, and you say you understand. 
But depression to you, is like colour to a blind man. 
I’m trying to breathe, but I’m drowning in a trance. 
I can’t take this, I can’t feel a thing, except numb and I hate this. 
My grave is this body, I feel broken and dead,
My visions gone out, And I can’t even see one step ahead. 
I can’t do this anymore, it’s too dark. 
I can’t breathe, I need your help, but it’s like you’re looking right through me. 
You see what you want, but I’m just trying to survive. 
But if I’m being honest, I already feel like I’m dead...
