Back With Her Ex

I need to have a drink
Or three or five or ten
Get her out of my head
I don't want this pain again

She got back with her ex
She left me all alone
I felt so high when we were together
But now I'm sinking like a stone

Do I even cross her mind?
Am I so easily forgotten?
I'm breaking down, decaying
Turning into something rotten

Drowning in my sorrow
Drowning in my drink
Coughing up the excess pills
Why do I have to think?
