Happened to me 3 or 4 times. My friend once made a new friend and started bullying me in 2nd grade. I told the teacher but, she didn’t listen…. And most recently, my friend who used to be my gf, we were the bestest of friends, but, I messed up trusting her. She went behind my back, dated my ex bf without my permission, and then ghosted me. And before that two other of my friends thought they were too cool for me and just straight up left me.
