Sometimes, I sit in the car and go nowhere

Sometimes, I cry my heart out for no plausible reason
Sometimes, I stare at the computer screen and do nothing
Sometimes, I plug in the headphones but don’t listen to the music
Sometimes, I look into your eyes but see nothing
Sometimes, I walk around in the square with no destination
Sometimes, I sit outside the house, dreading going in
Am I insane, I don’t know
Have I lost it, I don’t know
All I know is that calms down the fury inside me
It makes me go back and do what I need to do
