What the word gone means

I was looking for god in an empty cornfield, but all I found was dirt and trash. I was thinking of you while I was spitting at sunsets. I was thinking of leaving here for good.

I was looking for love in a Greyhound bus-seat, not feeling unlike dirt and trash. I was thinking of you while I was watching the sunrise. I was thinking of leaving here for good.

I was searching your bedroom for any signs of life.
Abandoned books and dusted keepsakes were all that I could find.
