Why is my girlfriend jealous because I talk about Eminem 24/7?

See I'm just like him in a way,
I never knew my father neither,
He used to always cheat on my mum and beat her,
I can relate to what he says in his songs,
So when I have a crummy day, I drift away and put them on,
Cause I haven't got anything else so that stuff helps when I'm
depressed,
I've even got a tattoo of his name across my chest,
Sometimes I even cut myself to see how much it bleeds,
Its like adrenaline, the pain is such a sudden rush for me,
See everything he says is real, and I respect him cause he tells it
My girlfriends jealous cause I talk about him 24/7
But she doesn't know Slim like I do, nobody does,
She doesn't know what it was like for people like us growing up.
