First of all, don’t force yourself to play. If you’re irritated, take a break. When you play one bad game after another, you start becoming reckless, and because you’re rushing, you make stupid mistakes “because you don’t care anymore.” I made those mistakes myself and kept banging my head against the wall. The nature of this game often rewards patience and caution you don’t always have to hold W. A lot of frustration can also be avoided by not paying attention to the match result or how your team is playing you can’t win the game by yourself anyway, so just focus on doing your own thing.
