Favorite game unplayable due to toxic community

I have been playing league for YEARS! League of Legends has always caused slight stress for me and sometimes made me a bad person. but most of the time I was a better person for league, I had tons of fun over the years, made some of my favorite memories and some of the best friends that I will never forget... well Sadly that is no longer the case. I have forgotten every good memory. they've been drowned out by toxicity and racial slurs. People calling me retarded, useless.... they even go as far to try to get me reported at the end of the game for getting upset at the way they're talking to me. They have no remorse. They have no care. The community has always had its kinks ( NA ) but its never been like this for me. Every game I play there are always trolls or someone being mean to someone else. Even if I'm not the victim I still feel bad. It breaks my heart that my favorite game Is no longer an escape but a personal hell. I sign into league and stare at the que button for almost an hour trying to decide if I want to put myself through this torture again. I usually try to be optimistic and say NO! this game is going to be different! This is hardly so. Im tired of this. Im tired of not being able to play this great game because of crappy people. No I shouldn't have to mute everyone when I join a game. that is just dumb. Like whats the point in playing if I'm not going to communicate with my team? if this continues I will regretfully be leaving Riot for good. This decision does not stem from the gameplay itself or the changes riot has implemented into their wonderful piece of art they call League of Legends, but because of the community that has crushed my soul and spirit. I should never have to carry the stress of a game into my real life. but sadly thats how it is. Im put down constantly on the rift and it translates to my real life. The harsh words echo through my mind as if I'm hearing voices day In and out. They effect my attitude and outlook on the NA population. This is something I can't keep doing to myself. Riot.... please help me. I don't want to leave.
