Matchmaking is turned against me

the game linked is just a perfect example what I have been having to face in most of my ranked games.

DISCLAIMER!! I AM NOT SAYING I AM THE BEST PLAYER IN THE WORLD AND THAT I PLAY PERFECTLY EVERY GAME!!

Game linked I as ornn did the most damage on my team when we had a kha, malz, twitch and lux. Bot lost as twitch as lux against a yas and naut and not just little loss as in almost int worthy loss with the tower falling at 8 minutes and yas final score being 20/6. Kha did next to nothing besides donate kills and complain that it was lost and threaten to go afk and malz would setup an ambush solo with only r and then proceed to get destroyed when it ended.

No matter how hard I try my team manages to get absolutely bodied in lane resulting in a hard loss. I thought it was a luck thing and with time I would get enemy teams that would do the same but the only wins I managed to pick up were barely had.

I am now almost 100% sure that matchmaking is targeting me and putting me with players that will guarantee a loss.

WHAT DO I DO!??!

At this point league is nothing but a draining and tilting experience and am honestly thinking of quitting only returning maybe to play an aram now and then with friends.
