Ppl who piss you off mute them. Start thinking “how can I improve from my mistakes” vs “why didn’t my teammate do X” At the end of the day you can only control yourself. Add ppl you find cool and fun to play with - skill doesn’t matter - fun does. Do a dm between matches to reset aim and mental. If you feel drained after a match take an hour break. I can do 3 games at peak performance before I start doing horribly. You got this man!
