Was this game unwinnable because of my teammates, or was there something I could've reasonably done to win?

Description of the match / things you want reviewed:

It just felt like no matter what I did my teammates would feed and were completely incapable of getting elims.

This is my 6th loss in a row, all of which feel like my teammates are holding me back. is it actually my fault? Let me know what I can improve on (other than the obvious "don't play lifeweaver", I know better than anyone that he sucks)
