Ineed advice. i have a lot of friends at school but recently my best friend for some reason didn’t like our friend group. she wanted to switch to a new table during lunch. she said she found a new table where we would be welcomed if i wanted to come. i agreed because i knew i would continue to talk to them outside of lunch. after a month or two, my best friend got mad at our new lunch table group. so she left for a day or two, but i stayed because i actually kinda liked it there, even if it was kinda crazy. then she came back to the table. eventually i started to miss my old friends at my old lunch table. so i went over there for one lunch. then after lunch i sat at my new lunch spot before the bell rang. they all called me a traitor. so now i sit with my old lunch group, which is fine because i missed them, but i also miss my new, now old, lunch table. what should i do? p. s. sorry if you loose your last brain cells trying to understand this.
