Yeah I’m definitely taking a break and I’ll try this afterwards. Thanks!
Turning off chat made a big difference for me, as did finding a champion that put me in the right mental. I noticed that playing divers/assassins actually tilted me more (probably because you die from mistakes?), but playing mages/enchanters (i'm mid/supp) kept me pretty chill.
I have chat on now, but I insta-mute the SECOND someone gets salty in chat.
