Something's wrong

Game after game after game after game I get placed with bot lanes who feed feed feed feed feed feed straight to a loss. What's most infuriating of all is I do exceptionally well these games, but I can't carry cause Timmy and Bobby fed 20 kills to bot lane. I'm now down from gold 3 around 60 LP to 0 lp gold 4 because of this. I do not feed these games and I always play well. Of course I make mistakes but never game altering ones like flashing straight into 5 people as an adc. I'm sick of it, something is broken with the matchmaking in this game, am I being placed with these people BECAUSE i'm doing well and Riot wants me to carry them? Sorry, but i'm incapable of carrying against a 20/0 bot lane and a 10/0 mid lane, I can't do it.
