What to do...

So, I just play a game that made me really frustrated. I was play Bard, I had an Ashe adc, Yorick top, Udyr jg, and a Talon mid. I went 2/3/20 and Ashe got fed early game. Everyone else.... not so much. They all fed causing us to lose the game. Now, I know we could have made a comeback, but with Ashe and I with the only decent kdas, it was not likely. I'm going back and forth between bronze one and two. I've come from bronze 4 and I really want to get out and get into silver. Any tips would be appreciated. :)
