What could I be doing wrong? And feel lost

Recently I got a wave of games where my teammates are just dying left and right. In about half of them I can manage to get big. However, I still end up losing since if I get killed no one else deals damage. The other half of the game I am not really fed but I am also doing well. Based on the net in almost all these games I am winning over the enemy jungler. I feel like I can 1v9 but not alone sort of vibe. Where if my teammates play around me and engage I can kill the enemy. But that’s not a factor I can control.

I don’t really split push as I feel like the enemy gets back to the lane too quickly and instead I can steal the enemy junglers camps. Could that be detrimental? Could be the reason?

Here’s my op.gg
