ranked is absolutely unplayable

Every single game i play, i have a team of feeders. It would be one thing if its just a game here and there. But i literally cannot win ranked games because my top laner will go 2/6, my jungle will go 3/10, my adc will go 4/9, and my support 1/6. When this same exact story happens every single god damned game.....what the hell am i supposed to do?! It'd be one thing if i could clearly see the fault in my own gameplay. But i tend to play rather well. Its just my team does terribly and im left standing there, like wtf am i supposed to do?! I'm just not allowed to win games apparently. I could go queue up for 20 consecutive games right now.....and i would bet 1,000$ its the same exact story in every one of em.....top lane feeds, mid feeds, jungle feeds, etc.....and im standing there with an 8/2 score like.......welp idk what else to do. its EVERY SINGLE GAME. not just here and there. EVERY. SINGLE. GAME.
