Past 6 Games, all have feeders on my team ;-;

Why? Why is my luck so bad

I enter a game, 5 of these 6 games my team gave up first blood. Each of these 6 games there has been a feeder on my team. Always on another lane or role from me. Why is my luck so incredibly bad the moment I entered bronze 2 ;-;

Here's a wonderfully comprehensive list: -Vi, 5/20/20, enemy Voli got fed and carried them -Xin, 4/10/8, Ali, 0/7/7, Singed, 5/13/3 (proxy), -Liss, 5/13/6, fed her Illaoi in lane until eventually ended up going 22/2/3, was actually unkillable -Bard, 1/10/7, Jinx, 2/8/5, enemy Lucian got super fed -Garen, 3/10, but to be fair he was lagging a lot (still bad luck, why was he on my team ;-;) -Riven, 3/10, got enemy Darius super fed And most recently, -Tristana, 5/20/12, got enemy Ezreal super fed no one wanted to target him so GG

I don't think I'm the real problem here to be quite honest. In 5/6 of these games I've died no more than 5 times, and the exception was only once the enemy team started becoming unstoppable.

I'm not understanding if this is just luck, or if its because I recently had a hot streak. I find it incredibly stupid that I get a loss streak if I've recently had a win streak. Balancing out winrate is not an excuse.

EDIT: Finally won a game, but it was a steamroll. Really makes me question Riot's matchmaking system. I didn't gain a lot of LP either meaning their MMR was much lower.

EDIT: WONDERFUL NEXT GAME I HAD AN AFK
