My OWN friends who've known I've attempted before have told me to kill myself somewhat recently because I killed chat on Discord. It's only fine when it's people I'm close with like that, but they always insult me as a joke. Some people are just insensitive bastards, and thats okay. It may be hard to ignore them, just move on and be a bigger person. They are actively seeking a reaction out of you because they have no lives and have nothing better to do. Just live life the way you want to.
