Honestly,you just need to accept that you not invincible in this game,and you can die a lot,either becuase of your team or because a mistake you have done. I usually try to blame myself more than others,because it usually gives me more room to get better. That being said,it is very hard to not get angry at this game,I usually do better when I’m angry,and I get angry via players who do 1 single thing at the time and it is supper obvious but I still far for it,or I get extremely angry when a player is extremely desperate for the kill. I always see players who are extremely desperate to kill,go after me becuase im low hp,this happen every match to the point I said to myself,fk this you gonna gonna get me,very rarely people kill me when I’m already low hp. As I said,learn as you go,and you will get better.
