So my younger brother is suferring from an acute case of high toxicity. Like it's disgusting seeing and hearing him play. It's almost funny now how angry a 14-year old can get over dying because his teammate(who he didn't call out to or anything) didn't peek with him and he died. He gets very angry on some really minor things like getting killed through the smoke etc. I feel really bad how much he swears and literally cries while playing a damn video game. He has also started acting very rudely to anyone who calls him or enters the room while he is playing. I am sure some of you must have dealt with such things before so I would like to get some advice on the same. Thank you!
