I've had it with Riot matchmaking

I am currently in gold 3, I know I have a lot to learn about the game, but here's my line of logic. For a gold player, I believe that I am well above the average skill level, both mechanically and game knowledge wise. I very frequently duo queue with my high diamond friend in normals for practice so I've had a lot of practice against people who are better than me. Both he and I are jungle mains so he's taught me a lot about counterjungling, pressuring lanes and objectives, etc. Previously, I've had a lot of success in my ranked games with high kda's and high winrates, but very recently something changed. Out of my last 20 ranked games, I've lost 14 and I was demoted from gold 2 to gold 3. I try really hard every game to maintain a positive attitude and in these losses I just don't feel that there's anything I could have done to salvage the game, mainly because recently, its just been game after game after game after game of feeders, inters, ragers, basically every kind of league player you wish would just crawl in a hole and die to spare the rest of humanity from their stupidity. Every game my laners push up, get ganked, feed, then rage at me and the rest of the team for not doing enough, and that just ends up snowballing into loss after loss. I don't care if you're faker, if two of your lanes go 0-6 and the other lane goes even every game, you're going to have one hell of a time winning any games. I've had bad streaks before, but this is something new, it literally feels like I'm being queued up with the worst gold has to offer over and over again, and I can't for the life of me understand why. Even bad gold players can win 40 - 50% of their games just due to pure statistics, and yet here I am, a player who isn't bad for his elo, just getting dumped on every game. I don't understand, maybe Riot just hates me.
