help please copycat situation

i have an ex best friend who i recently patched things up with. she was my ex friend because she got into a relationship with my ex boyfriend right after we broke up and so i just cut her off. they are still together but since i didnt patch things with him (and hopefully never will bcuz hes evil) i figured it wouldn’t matter.

We show up in each others feed, mutually like each others posts and everything felt peachy until a few nights ago.

It started off as me posting a timelapse of me cutting my hair into an emo fringe (which i do periodically) and 2 days later she posted herself at a salon getting the same haircut. i ignored this since i thought maybe i inspired her and it’s also hair so i don’t care much.

The next thing was so direct i couldnt ignore it: i posted lyrics to a brand new song (i am heavensent dont you dare forget) and she posted a few hours later “don’t forget i am godsent”. imo this was so stupid and i didnt wanna be like “that’s not how the song goes” because she was clearly just doing it after me and thought it was a quite or something.

things went downhill from here, she posts hours after i do with the same subject matter: i posted a note with a joke i cant repeat (whoever has my voodoo doll —————) and she posted the same joke with a changed word or 2. Then again when i drew cat whiskers in pink on a pic of me and she did the exact same thing. theres also a star motion i do with my hand in pictures that shes started doing that shes never done before.

Yesterday, shit really hit the fan. i have a large scar on my inner thigh from self harm, it’s embarrassing and hard to miss whenever i wear shorts or even skirts. but yesterday she posted a photo with a bandaid covering the same area with the edges of the cut peeking out of the sides.

im becoming paranoid because i’m not sure how to confront her. i don’t know if i’m overreacting and being worried about her copying me so much that i’m looking for things i might perceive as copying. i don’t know what lengths she is willing to go to copy me. i don’t know and i need to know something. can anyone help me?
