Checking out of reality so much via daydreaming that I forgot how cruel the world was (even though that was the exact reason I started escaping reality via daydreams as a child...) until it was too late and I steered myself right back into the same hell I somehow managed to escape from as an adult.
Maybe with my new experiences I could have transformed that situation into something liveable, but instead I doubled down on the same coping mechanism until everything has become very very messed up.
