I'm nearly tired of Ranked

I have been playing League for little over a year now. I've had ups and downs, been frustrated and felt joy, and I've never felt aggravation as severe as it is in lower elo's. I'm Silver 4. I'm not saying I deserve Challenger, or that I even deserve to be higher than I am at the moment. About 2 to 3 months ago I made the climb of my life in League: I went from Bronze 3 to Silver 2 in about a week. I know that's not that great of an achievement, but for this being my first season of ranked, I was proud. I took a short break from ranked because my friend whom I was duoing with was moving, so I figured I would wait to climb until he was back on. This was a terrible mistake. The momentum I had in League and in ranked had dropped, dropped me back down to Silver 5, 0 LP. I was in fear of being in Bronze again. I went on a few winning streaks, got back to Silver 3, and was happy again. However, the past month has been complete hell. I can't tell you how many queue's I have had to dodge because I had a Teemo jungle, or AP Shaco support. I can't tell you how many times I have tried to convince my team mates that this certain call was better than what they wanted to do, but instead I'm blamed for not being there. I can't tell you how many almost-guaranteed wins I've had, just to be thrown away because our Vayne decided to farm top when she's full build and we're engaged on in our base. I'm not blaming anyone for these losses, I just see so many stupid calls and decisions being made and it costing the game. I've made my fair share of bad decisions, bad calls, stupid deaths and near-r%%%%%ed attempts at doing something good in games. However, I have never trolled in champion select. I have never said "mid or feed", I have never Zilean jungle just because I saw Cowsep do it, I haven't made people waste their time in a game on purpose. Ranked is supposed to be where you show everyone you're great at the game, not make 4 other people wish you had Ebola.
