Flame and Move On
So for the longest time, I was the least toxic player imaginable. I never was rude, never criticized for mistakes, etc. I had always heard high-elo players preaching that elo hell doesnt exist, and that the only reason you should ever lose a game is because you couldn't carry. I adopted this attitude, and for about a year I believed that every single game I lost was my fault.
Then it came to me.
I can only be expected to do my best, so blaming myself for not carrying a game even if I played to my fullest potential makes no sense. Some games (some, not most) CAN BE LOST BY TEAMMATES.
Me realizing this led to me developing a new philosophy in league. Rather than shouldering all of the blame for losing, I developed a mindest I call, "Flame and move on". Basically, when a teammate does bad and isn't apologetic, you reprimand them sternly ("maybe you should play champ x, they're easier than champ y" or "I hope you realize you're the main reason we lost") , but not crudely (no "kill yourself" or "get cancer"). The purpose of this is to alleviate stress at the prospect of losing due to a teammate. "Flame and move on" has made my league experience much more enjoyable, because I'm no longer blaming myself for every little thing that goes wrong, I'm sharing the blame to those who actually deserve it.
I highly recommend that you try adopting this mindset. It's helped me get off tilt faster and view the next game after a loss with a more positive mindset.
