I'm done...

I can't take this anymore...

I played a game just now where it was me (Rakan) bot with Jhin. We get fisrt blood. Enemy Ashe leavse game.

Guess what? Mid, Top, and JG all feed enemy Vlad and Yi. I tell them to stop feeding, to which they say "we're only 0/2". I tell them that they just gave 4 total kills to the 2 best scaling champs in the game. I die in a 3 v 3 top (Top finished game 2/7, Jungle 1/9, and Mid 1/8. Bot Started 2/0 for both, then hit about 4/4 mid game due to every other lane feeding, and end 5/8/3). IT'S A FUCKING 4 V 5 AND MY TEAM CAN'T WIN.

I'M SICK OF THIS SHIT MAN. WHAT DO YOU HAVE TO DO TO WIN.

I have ACE in 9 of my past 27 games (note: would be 30 but 3 of those were clash that don't count). I have 18 losses out of my past 27 games, of which 9 of them I was the best player on my team, and second or third best in the game. Of the remaining 9 games, only 4 were bad:

Lee Sin JG going 0/5 Cait going 0/6 Darius going 2/10 Karma going 0/3

Other than that, I have been the first or second best player (using op.gg's ranking system telling you 7th, 8th, 9th, etc) on my losing team each game.

HOW DO YOU WIN. How? I don;t know what to do anymore. I have a 33% winrate despite getting ACE/MVP in 10 out of my past 27 games, or about 37% of the time, or getting ACE in half (50%) of my losses. In my past 50 games, in my 26 loses, I have gotten ACE 11 times, or about 42% of the time. I am consistently one of the best players, not only on my team, but in the game. But I lose. NO matter HOW WELL I DO, I lose. I just can't win. NO matter what happnes, it is a loss. Why? What am I doing? I'm taking towers. I'm doing shit. At this point, I feel like I'm going insane especially with the last game. I honeslty feel like Riot's matchmaking is pure dogshit-I am CONSTANTLY one of the best players on my team-STOP PUTTING ME WITH DOGSHIT PLAYERS. If I am doing so much better, stop putting me with these shit players who feed the whole game, every game.

Is there any advice you guys have? Should I take a break? Should I do something else? I just don't really know what to do anymore.
