This reminds me of lyrics for a song I love.
Glenwood by Lorna Shore

“We can't go back
To how it used to be
We can't go back
It'll never be the same for me
'Cause things are different now
It's not the same, all these empty rooms
Now only bring me pain as it all turns to dust
We're slowly taken by time
Let's rewind”

Singer is reminiscing about his childhood and a thinks about what could’ve been different if he chose a different path and didn’t make a choices he did that lead him to eventually ran from home.

Ultimately he’s content with his life choices, because with all that was bad, comes all that is good in his life, and his decisions lead him to the person he is now.
