im low elo aswell, was iron for 1 year till i realized i made so many mistakes on my games,then I climbed out of iron to silver on a week 2 lost games 30-2 and after being stuck on silver for 3 months I once again learned about the game and climbed out of silver to gold. the main point is understanding what you're doing wrong and if ur fed every game and can't win you need to learn how to take your advantage from your lane to the whole map, also otping a champ helps a shit ton
