Elo hell must be real

I've heard it a million times that elo hell doesn't exist and I personally believe that this is a true statement. If you carry hard enough or manage to organize your team you should be able to win any match up. Today i lost 5 games in a row of ranked play. In 3 of these games I had members of my team that had scores of 0 and 10 and even worse. In one, our adc went 0 and 16 while his support managed to keep a healthy kda through rotations late game. His support was good, better than average and he performed well mid to late game when we started to make more team plays. The adc continued to feed throughout the game and buried us under all his weight. In all 5 of these games I had a very positive kda of an average kda of at least 3 or higher. My cs in all of these games was 200+ and in one, it was even over 300. I adjusted my builds to account for the weaknesses in our team but the trolling and feeding of certain teammates just prevented me from winning no matter how dedicated I stayed to the game. To sum things up, I'm now in Silver 4 and I was in Silver 3 this morning. I lost 90 lp today over 5 games in which I dominated my lane and successfully executed many ganks. Elo hell may not exist, but being consistently trolled does. I was in promos for Silver 2 four times this week. Every single time there would be an afk in at least one of the games. In a few I had junglers that didn't gank or even sate their devourer. They just split pushed the entire game as they hit 35 minutes with a regular, useless devourer. I had trolls tell the rest of my team we didn't deserve to win as they intentionally fed the other team. This week it seems like I've experienced every possible extent of trolling and it's heavily preventing me from making any progress and I honestly just don't know what to do. I'm basically losing interest in continuing to play the game because the general community I've experienced is either too mean or just too trolly. If anyone has anything to say I'd just appreciate another opinion
