if they say you should die because you wanted to talk with them, they are not nice people. you should avoid them for your own benefit. try to find other people if you can, but I would say being alone even is better on a scale. I was in a similar situation for years. and when I thought it ended, it all came back with other people for another few years. if you are a child in school, locked together with them, mentally prepare yourself that they’ll continue bullying you even if you don’t contact them, and that most teachers won’t care. still, you should try getting help if the madness does not stop.
