I thought I'd contribute the first interpretation...
I think this song is about friends and associates trying to help out but coming across as attacking and condescending even though they don't mean to, and feeling like they're all against you. Sometimes it might feel easier to drown in "quick sand" than to take on board what these people are saying. And finally you realise things and figure things out, but you still need the help from those same people.

It seems like a thank you to me.
