Getting into plat 5 elo and I can't carry

What in the actual f***? I can't carry anymore.

I picked Jayce mid. My jungler Shaco comes at level 3 and fails gank but burns enemy Ahri's flash. Okay.

But then he goes in again alone, feeds her double buff by chasing under tower then getting charmed. Okay.

[slayer-jinx-unamused]

To this point, I said nothing. I just let him be. Maybe he just f***ed up. Okay.

[slayer-jinx-unamused]

I get a kill on Ahri. Okay.

[slayer-jinx-catface]

I manage to get another kill on Ahri but Lee sin comes to clean up. 5/0 Lee Sin. Okay.

[slayer-jinx-unamused]

Our team is getting destroyed. But no one is really saying anything. We are defending. Okay.

[slayer-jinx-unamused]

I manage to go help bot lane and pick up 2 more kills. Okay.

[slayer-jinx-catface]

I am sitting under mid tower and our jungle is completely unwarded. Okay.

[slayer-jinx-unamused]

I try to stay on the top side and get 3 man dove by Alistar, Lee Sin, and Ahri. Okay.

[slayer-jinx-unamused]

Lee Sin ends game 18/1. Okay.

[slayer-jinx-unamused]

Shaco ends game 3/12. Okay.

[slayer-jinx-unamused]

Well I just lost game.
