I also had a nasty falling out with an ex-friend. Multiple, actually. I'm moving on from her by surrounding myself with good people, though. Sorry to hear you had a shitty friend (｡•́︿•̀｡)

"haunts your narrative" is such a good way to phrase it,,, it used to be this old friend group i hung out with everyday when we were very little up until highschool,, but nowadays i dont think about them anymore bc i try to not keep in contact with them except for bday wishes and stuff. hmm,,, maybe myself then. im always thinking of past mistakes and doubting myself,,, its sooo bad
