Bad Teammates

I understand the idea that "if you're not climbing it's because of you" but I feel like my teammates make it impossible to win every game. I get AFKs and leavers 60% of the time i solo queue, and if nobody leaves, somebody feeds. The game just wants me in bronze. Yes, I understand that some of these games are winnable, even if you don't have "teammates", but I'd literally have to be a diamond player in order to carry my team that hard. I'm not sure what I was expecting by writing this, but if anyone has any tips on how I can fix this, let me know. Is anyone else having this problem?
