There are so many lines that I've crossed, unforgiven
Swift's inability to forgive herself for past mistakes is something that has haunted her for a long time. She told Rolling Stone
: "That's something that does bother me, looking back at life and realizing that no matter what, you screw things up. Sometimes there are people that were in your life and they're not anymore - and there's nothing you can do about it. You can't fix it, you can't change it."
Swift added that the pile of old selves fighting each other in her "Look What You Made Me Do
" video references this struggle to deal with her failures.
