Conor Oberst says it too well

"Now I walk around in some kind of altered state.
The drink in my hand is starting to shake.
I get used to it if it has to stay this way.
A new bunch of flowers I'll have to arrange. 

I don't want to eat or get out of bed.
Try to recall what the therapist said-
Ego and Id, the Essential Self,
You are who you are and you are someone else. 

But I'm worn gossamer thin.
Like Delicate Arch, carved by the wind.
There's a glass psyche at stake.
Throw me a brick, see if it breaks.
'Cause the mind and the brain aren't quite the same
But they both want out of this place."
