Me and my best friend made a girl think she was insane and that nothing was real..

So this happened when I was in 5h grade and this girl let’s call her H was my best friend and still is. Basically I would do whatever she said and I was like obsessed with her and making her proud of me so whatever she asked me to do I would do it. So these other girls let’s call them O and R me and H were friends with O but R had joined our school in like the middle of the year and acted really weird like putting Bambi in her mouth in the middle of class, acting like she was in a movie and randomly singing out like she wa the main character, and one time she tried to stab H so me and H hated her and were really annoyed hy her but O wasn’t and was actullly her friend and me and H were jealous and we thought R was taking our friend away so we started to bully and make fun of her when we could but it got bad one time. So it was a normal day at recess and me and H were talking and we saw R just standing on the field singing again so H came up with the idea of acting like we were robots and going up to R and telling her nothing was real and she was just imagining everything and it was all in her head. So I obviously agreed as I told you before I would do whatever she said so we went up to R and walked in front of her not talking until she said something. After she said that me and H would talk in sync and tell her how nothing was real it was all in her head and how none of her family cared for her and sent her to a asylum to just get rid of her and we were doing this for like 10 minutes until she started to break down crying and we just laughed and walk away and R was sitting down crying for the rest of recess and me and H never got in trouble. I still feel bad for R till this day since I know what I did was fucking rude af.

Let me know if you want more confessions since I got a bunch more
