Something is seriously wrong with matchmaking.

I'm literally past the LD50 for alcohol consumption, and for those of you who don't know, that's the point at which there is a 50/50- chance of literally dying for consuming so much of one substance. I stomped my lane regardless, even though I was autofilled to my second worst role, top lane, and my entire team just fed, until I said "Just stop dying for a few minutes and I'll carry.", to which my support responded "nope, your turn." and came to my lane, inting 3 kills, before saying "ff at 15". How the fuck am I supposed to climb with this bullshit? How can I, as someone who is literally so drunk I have a 50/50 shot at dying for drinking this much, actually be the best person on my team? How am I supposed to carry if my team griefs me because I'm doing better than they are? Horse shit game.
