issues...

I quite literally hate one of my friends so much! Lets call them 'poser.' literally there one of the worse people in the entire earth! They are so two faced and toxic! They literally encouraged one of my other friends that she was gonna get them a eyebrow razor to go even deeper and then proceeded to say "lets match!" WHO SAYS THAT?? omg.. why are they encouraging somebody whos struggling with sh to continue.. then she also ruined my life by lying, bullying, and talking behind my back and also telling my business to other people! Then she also ruined like 4 other people life along with trying to do that to 2 other! Plus poser always lies about loving metal, loving nu metal, being alt or whatever but isnt political nor listening to the music. SHE LISTENS TO KPOP!!! What do i do... we been friends since like 2nd grade.... poser always copies whatever i do.. like i drink water she does to, i put my flute down she does to.. i grab my phone and watch tiktok and then pause or like a video she DOES TO!! ITS INSUFFERABLE. NOW ALL OF SUDDEN SHES ACTING DEPRESSED. Like today at school she made herself left out, we even asked her if she wanted to join or if she was okay but then acted mysterious... it gave very ignoring and attention seeker! I NEED HELP WHAT DO I DOOO AND WE WERE TALKING ABT SPACEHEY IN FRONT OF HER LETS HOPE SHE DOESN'T JOIN....
