Why does League Of Legends make me so angry and anxious?

Ive been playing LoL regularly for about 5 or so years now, there have been many times where i dont play for months at a time, which are the times i also feel least anxious and stressed in my normal life, quitting LoL is something many people want to do, but why is it so hard to just quit?Sure you can uninstall, but youll just reinstall and continue, ive tried quitting so often, i currently have 11 or so well deserved perma banned accounts for various reasons, but after every ban, i just create a new account, every time i play LoL, i feel angry and i get anxiety and impatient for a fix, for a fix that seems eternal and will never come, ive played alot less more recently, and not because i dont want to play league, but because i dont want to have built up anger and anxiety that completely puts me in a bad mood, and of course, the reason is usually the teams, yeah im definitely not the best nor close to it, but why do i usually have the best KDA,CS, and objectives on my team?Even when i play really good, i will not continue to play because i know that good mood will be ruined within a couple of minutes in the next match, i had a game where i was 17/0 or something like that, but decided not to play for a week or so because i knew what anger and anxiety was waiting for me the seconds i press find match, just now, our team starts off the game as 6/1, with all 6 kills being mine, and us losing because our ADC wanted to afk after his first death, this game is addicting and not fun at all, the only times this game is ever fun in the slightest, is when i only play to troll or lose on purpose, even after dropping from Gold 1, plat 4 mmr, to gold 4, i still play this game, because i feel like i need to play it, theirs no way to quit and the game is not fun enough for the mental harm and anguish it causes me, i dont know how to quit, and i dont know when to stop playing, if anyone got any tips for me, id definitely love to hear them
