Being between life and death

Used car

I've lost all motivation
My brain has came to a halt
And I'm finding it hard to restart
I am not a mechanic
I cannot fix this broken heart
The steam is to much
The metal is to hot
It's to much
It's to much
It's to much
I must start learning
Not about cars but about hearts
About yours
Because everyone seems to ride you
You are a car that's always used
And you only come back
To me
The mechanic
Just to fix you up
Then you'll leave again
