AITAH for switching up on my friends?

So i was friends with these two girls Sam and Rachel who bestfriends and they were basically like regina george and gretchin from mean girls. And then i became a lot like Rachel i was basically her minion or flying monkey, i basically became karen which is the best way i can put it 😭 I knew deep down I was in the wrong for staying by her side and deep down i did secretly resent her for the way she treated both me and other people but i just stayed being her friend when i know i shouldn’t have. Not only did i stay her friend but i basically became like another version of her and started treating other like she did.

Well anyways then i stopped hanging out with them a lot and distanced myself. But we still were in the same friend group because it was like one big friend group split in two and so there was Rachel, Sam and their friends and another group of 5 girls. So i basically just switched to the other group because they’re much nicer and more chill. And i figured rachel and Sam wouldn’t care and just let me go since they had others to replace me.

But then after about a week their side of the group stopped talking to the other 5 girls. And then, on the huge groupchat we had with all of us on it, they blew it up saying things like “if you have any issues with us can we sort it out we’re trying to be mature” and things like that. None of me or my friends responded bc they were obviously trying to group bully us or intimidate us (particularly me) they then made comment that they claimed were jokes like “two faced r3t4rd” (which i knew was aimed at me) and saying they were gonna shank someone with a knife. They also then messaged some of my friends saying “this isn’t aimed at you and im sorry about this” basically proving it was all aimed at me.

I then got really like pissed off the next day so i handled it VERY immaturely and called one of them a nobhead to her face. And then that turned into a whole other thing so i eventually decided to just message the girls directly to see what they had to say. And basically they were going to confront me on the groupchat for “ditching them and hanging out with people who i claimed to not like” which i did do, but i only claimed to not like them because at that time i was scared to go against anything Rachel had to say because i was literally like a minion to her 😭 Well yeah and then anyways i called rachel a bully and told her if she doesn’t stop talking to me or about me i wouldn’t let it slide.

So then the next day they i reported them to the college and Rachel and another girl got suspended.

However in doing this i lost a lot of friends (which i knew would happen when i stopped talking to them anyway) and they turned a lot of people against me. And now they’re trying their very hardest to turn others against me and turn even my friends against me and making up lies and rumours about me.
