New Jersey---Where even the graffiti is depressing

I was on the AirTrain at Newark airport today and we passed over a regular train track where a cargo train (is that the right term? Is that even a thing at all?) was passing by. Naturally the train was covered in graffiti. On two cars in a row, in different handwriting it said:

"I am trying to keep myself
but my self keeps slipping away."

"Lost in life"

I had to break into my emergency stash of Valium and airplane bottles of Jack Daniels to even make it through the rest of the trip.
