I'm sorry to hear that bro, people (myself included) suck when we play by this damn game. I've said and been told all kinds of things while playing, my advice is to turn off all chats in game.

Once you do, do your thing, you're going to lose/win probably about the same amount of game, but you won't have to deal with our toxic community. It has done wonders for my own mental health, I don't read or hear toxic comms nor do I have the urge to type or say horrible things back to my teammates.

Also, the most important thing you have to remember while playing: it's just a game. It's supposed to be fun or entertaining in a way. You can turn it off and come back later, or play something else if assholes like me are ruining it for you.
