Riot, what have I done to attract your hatred?

I was sitting at Silver 5 and around 40 LP ( I believe, might have been a bit higher or lower). I had placed Bronze 3, and had worked my way up to Silver 5 in like 80 games. I then struggled to get out of Silver 5, reaching my promos several times back in June but unable to quite make it. I decided to try and go for Gold before the end of the season starting at the end of August. I found a champion I was really good at, and in two days went from Silver 5 to Silver 3 undefeated. I then got to Silver 2 within the following week. That was the start of September. In the past month and a half, I have been in Silver 1 two or three times. Each time, I get about 20lp and then run into a losing streak that drops me down to Silver 2. I didn't expect it to be easy, though, and l took a bit of a break when I recently got a new full-time job. I have now been attempting to get back into Silver 1, but Riot, what the hell did I ever do to you? I give you my money, and you give me 1/16 bot lanes. Every. Damn. Game. Or, if I'm lucky, an intentionally feeding jungler (and I do mean intentionally feeding) to boot!

Riot, I beg you. Fix your Matchmaking System. I know I'm not the best player in the world, or even a great player. I have bad games, and my performance in my secondary role is mediocre at best. However, my only chance of winning should not be me trying to solo carry against a 15/0 Vayne. I should be able to expect my teammates to hold their own. Yesterday I was able to win two games in a row. Today I lost all that LP and am about to demote to Silver 3 for the first time. I've been in Silver every season that I have played ranked, and this time I wanted to finally get out. Why are you making it so hard for me?
