Dude, you have a 47% win rate in ranked. You're grinding a ton of games, and losing a lot of them, especially recently. Last 10 games, you've won 3. You need to take a break. You've been silver for the last 5 seasons (I'm not saying this insultingly). If you want to get to the next level, you have to modify what you're doing because you can't modify what other people are doing. You have 300 games (!) this season so far, that's a lot, and what you're doing right now isn't working.
You need to take any champion with a losing win ratio and put them on the shelf. No more Xayah, Vayne, Jhin, or Neeko. Practice some different ADCs. Try new roles, and more new champions.
You also have so many matches that end before 30 minutes it's not even funny.
literally all them were over by 5 min
Stop surrendering ranked games. Do you know what people do in silver? They throw games. They don't know how to end with a lead. Your job is to hold in there until your opponents throw the game.
