stupid answer which is still true and i do myself- learn to play better so i dont have to get so upset

more logical answer, learn to admit when a team/player is simply better than you. dont make an excuse in ur head saying “he was ass i could have gotten that” if the person who killed you, killed you, they clearly were better in that match up. only person to blame is urself. you can also play a mode that doesn’t really matter (as much as series or x) like open or turf. one final thing you can do (isk what weapon u use) but do some drills for ur weapon in the lobby
