I am freaking tired of this matchmaking in the promos

I have lost my silver 3 promos TWICE in the past two fucking hours and it is pissing me off. First series, 3rd game, I play the game of my life with Annie- 21/5/19 and still lose because of an awful jungler and bot lane. I go back to normals, smash shit with Diana and get back to a series. Lost the first, came back to Annie in the last. Same fucking thing- bot lane sucked and we had a Twitch jungler of all things. We lose it to a fucking Teemo back door as we are pushing their base.

I am pissed right now. Last season I probably lost my silver 3 promos about five times, and now it's been twice. What the fuck do I need to do to fucking pass this? And I'm about sick of the matchmaking in League, not to mention the snowball fiesta that goes on. I miss season 5, at least it was more fun and not so self centered.
