From my perspective it doesnt have to be about selling out, but finally seeing an end to a situation or relationship and coming out feeling empty as if it was all for nothing. A real disgust for a situation or time or place, the line " apologies to all for the asshole i am" just shows the indifference of the songwriter, covered up by feelings of being burned out, that point when you just dont think you can work another hour at your job, or stand another minute fighting with your girlfriend or another drink at the bar.
