Elo hell

I'm tired of losing games because of bad teammates, it's not a matter of just being positive or maybe I'm the bad one, it's that the top laners feeds, jg never ganks or feeds when he does and bot might feed to. So top feeding is my fault? I'm sick of winning bot lane or at least doing decent mid when we lose later since top or mid is feeding and we can't win a single team fight, it feels like normals because all they do is say lol when they die, why the hell is feeding funny? I'm so sick of this, sorry for the rant but I lost over 30 lp today from feeding laners, not cool
