How the hell am i supposed to deal with such heavy feeding

So...i picked WW top (unconventional pick ik, but its my compromise to consistently getting first/2nd pick), but anyways, i'm doing just fine, in fact im getting fed asf...but at the same time my team is feeding 2 assassins....how am i supposed to deal with this...by the time i had 7 kills, both noc and diana had 7...and while i could take them out individually, fighting them in a tf resulted in both of them focusing me....meaning i would be blown up, and due to them being different damage types i couldn't build fast enough to counter their dmg
