Ranked is pointless

So a few days ago I played ranked for the hell of it and I went from Silver 5 0 lp to my promos. Took a break for two days came back played some more ranked. From the span of less than 24 hours I went from promos to 0 lp. Now I wasn't even doing bad I had great KDA and farm and I tried to push my lane as much as possible(Playing as fizz so I mean its not that hard) the issue was that my team was dragging me down. Two of those games ended the exact same way my team decides to do baron when the enemy team was up and we were down in kills/gold. Enemy team takes baron then wins.

Now after ever match I felt the same feeling of anger and pure hatred for everything about the game, yet I still played again after that. Eventually my last two games I went 0/9/X because I had just given up. Now looking back at how angry I've felt this whole day because of this game, specifically ranked I just feel hopeless.

"Don't play solo/duo play with friends or a team" to which I say I would except most of my friends playing this game quit about a year ago and even I don't play this game that much anymore but since I'm back home for the summer and my pc is sub par this is one of the games I can play.

I still remember what It felt like playing with friends late at night and even then we would get pissed but it was better with a group. Now I live in a different time zone and most of us don't stay in contact with each other anymore. It feels kinda lonely and I don't understand why I still play sometimes.

I hate this game, not because of broken champs or items not even because it is "not the game league used to be". I don't hate it because I think it's dying. I hate it because it ISN'T dying... And it keeps pulling me back in.
