Every feel like your account is cursed?

Every since I started playing League, I've been working hard to improve, I help my team when they need it, roam, main two roles, have a onetrick, etc. It was great, each year I kept going up in ranked. As a matter a fact despite being placed in Silver after placements for 3 years straight I still climbed out. From bronze to silver, learning improving, to gold, learning improving. And on Season 7 I got to platinum V in less than 60 games at the start of the season. Crazy right? And then one day..... I started losing. I mean people say you go on tilt, alright so I stop playing ranked, play norms instead to keep up my mechanics. Okay I'm still losing. Now here's the thing, when I was winning 5-10 games in a row I was at peak performance. When I lost in my games, I never changed my performance, but this wasn't just me saying I deserved diamond, maybe one day, but today I was Platinum, my elo had gotten all the way to Plat 3 while at Plat 5. At first I believed I was on tilt, would lose 3 games and then win 1. Then there would be days where I wouldn't win at all. Before every single game I checked on op.gg my team and while in game I checked everyone's ranks and elos. Majority of the time my team was either low in elo or on massive loss streaks. I mean surely there should have been a balance right? I then started dodging my first game's of the day because I found that when I did that my 3-7 game loss streak teammates would disappear and then I'd win the game with my new team five minutes later. But my winrate was not going up. I had a 70% winrate at the time and it was dropping fast. I still took the time to watch replays, be conscious of my actions, get tips, pay attention to the meta. But it never mattered how well I did or how much I helped my teammates, I would get lanes that would relentlessly feed, afks, trolls who inted or ran it down mid. I reported them like I should but surely this wouldn't last right? Wrong. It ended up turning into me winning a game every 5-6 losses, my elo was tanking even with my shiny rank on. I even went out to recruit friends of much higher elo than me to help me "break the tilt" and to my surprise not even they could win ANY games with me, even though they could at the start of the season. Even if we both did great the games turned into 2v5s since our teammates who were supposedly high gold/plat were somehow unable to play the game. So this continued until I had a 0% winrate for months, MONTHS. I couldn't win a single game no matter what mindset I went into it with. It didn't matter if I won my lane or somebody elses, rarely did I get a game that lasted more than 25 minutes, and my teammates were either plain awful or uncooperative. Then I finally descended out of platinum, all the way down to gold 5. My winrate dropped to the 40% and once it did I went on a win streak. The worst part was I didn't even have to play the some of the games, it was basically an automatic win. So I end up being able to get all the way back to Gold 2, but even then I was bouncing around promos like ping pong. Now we come to season 8, oh glorious season 8. A new reset, I should have the time of my life. But nope, not at all. I constantly get teammates who die so frequently, it's absurd. Apparently if someone dies 15 times in a game and I ask them to stop, I'M the PROBLEM. I get told that I need help, medication, but three teammates have a total of 38 deaths, and here I am with the jgler and we average at about 4 deaths in total. Constant games where my teammates relentlessly feed, I don't even talk to them, they just keep walking into the enemy team. From getting all the way into plat, those games nobody died within the first 5 minutes let alone 10. It took probably 15 minutes for someone to get first blood, that's how careful it was. But here? "Just chill bro" says the 4/9 camille, "we can still win" says the 2/11 illaoi. It's gotten so bad that in some of my games I get outright ignored by my teammates. Let me add I have not actually said anything other than game related thing such as "jgler top" etc. So there's a free baron, and 4 of the enemy team are on 40 second death timers, and my team does not take baron. They don't take baron. They ignore all my pings, everything I've said, it's like I'm playing with bots. When 5 of the enemy team are grouped mid, 3 of them engage for some reason, they WON'T back off. They REFUSE. I try to save 2 of them at least AND THEY STAY ANYWAY. So here I am losing yet another game because I literally got ignored. Yesterday me and a buddy of mine lost a game when our support was top lane dueling a garen; while the entire team called for his help he didn't even budge, didn't die either, just didn't leave the spot, didn't help nothing.

So if I do every get on a winstreak of 2 or 3 games or manage to squeeze through a promo, yet again, I just need to queue up for yet another game and see that my entire team are players on 5-8 game loss streaks or 4% winrates yet they're somehow in silver 1. And let me just add that I do have a smurf, and I was able to get my smurf into Gold very easily, but not on my main account.

And now I am Silver 2 and hopefully one day I escape this elo hell.
