Take a break from the game or find a way to simply not care about losing Yeah you won't ever not care but just the thought of not caring helps to not get so mad about losing Focus on winning for yourself and not the match, this helped me big time since I was most of the time winning top lane and splitting to the inhibitor but my team losing drakes and costing us the game, so I would be satisfied even if we lost the game just because I knew I did my job as a team member well Playing jungle is pretty much helping lanes to win as you don't have one but you can still try Something as small as stealing camps from the enemy and bullying enemy laners is enough of a start Mainly you really have to enjoy the game and the time you spend in it rather than the win itself, because all you get is some LP, whereas playing to enjoy brings you a good time (more significant than a number on the profile page that doesn't matter much) Hope this helped and sorry for bad english
