Not sure if this will work or if you've tried it before, but have you ever tried ignoring their bothering whims? At least it works for me, and I'm happier now. Just note that I've been bullied for like 7 years of my life. After my mom told me to just play along and don't bother about it, the bullying stopped. Private schools are dangerous.
My country has just recently got permission to do our own premilinaries, so now we hang out whenever a tournament is being held somewhere around the city. Plus, she's finally entering the competitive scene. I myself haven't been on about competitive battles since the 4th gen.
I prefer formulas over text, and text over those pieces of abomination that we were forced to memorize which doesn't have anything formula or text-related.
