It’s a fine vocal piece in a very workable range. I don’t really see it as a funeral piece, but your mileage may vary. It seems to say, “I screwed up when I was young, and my life has sucked since then.” That’s not how I feel about my life.
I see it as a song about life humbling you and how youth is wasted on the young...but I see how most listen to the words and hear what you are hearing.
